Hi Gregory, I just loaded the link you sent on my Android phone and the locate button worked as expected. Can you verify that you are sharing your location with the browser?

It looks like you've modified the the app outside the builder so it has additional. One of the contributions (FID = 31), contains an invalid character (line break at after text) in the new author field you added. Because of this, the feature service exports invalid JSON which break all apps that attempt to read this JSON including ArcGIS Online and the crowdsource app. These apps will freeze their execution when they encounter this feature. To fix this, you'll need to delete or edit this feature to remove that character.

In all cases most modern browsers will reject an app's request for location if there are any insecure scripts or iframes loaded on the page. Internet Explorer and some older versions of other browsers will still provide the location to an app even though it is a security vulnerability. In your case the web app builder will work in every browser except the latest version of Safari (Safari, added more rules that requires all content to be requested over https, including images) because their is a secure connection for all scripts and iframe. However, as I mentioned, there is not a reliable way for apps to determine if their connection is secure and then display the button in only these cases. The Story Maps team has decided to take a stronger approach to determine when we display the locate button. Because many viewers of story map apps are the general public we try to make our apps as simple to use as possible. We have chosen not to show the locate button to users if they will constantly get a error message that their location cannot be determined. Even if they double check their device location permissions they will still always see this message which leads to confusion. Also, we want to follow security best practices even if an older browser leaves this vulnerability open to attack. Especially because a public user has a higher likelihood that they are accessing the story from a public wifi hotspot where these attack are more likely to occur. One other note, I looked at your story and it appears a couple of your tabs have private content in them that requires a login. Make sure to test the public version of your app from a browser you don't typically use and when you are logged out of your arcgis online account. Unfortunately, private content that requires a login from ArcGIS Online and many other services will not allow their sign-in page to be embedded and the app will not load. This is security vulnerability because the parent page or other scripts may try to steal the user's credential. It may look like it's working for you because if you are still logged into a service the embedded app can authenticate with a browser cookie instead of redirecting to a login page.

Kelly, It looks like the basemap in your shortlist app is a custom basemap that is hosted on an Amazon server. The server you are using does not have a https certificate. In order to enable location, you app must user a secure connection. However, when you choose to load you story map over https, the browser will block all requests to insecure connections (including your basemap) and as such your map will never load. This is a security restriction the browser puts in place and we cannot override in our apps. If you would like to continue to use your custom basemap, you will need to add a https certificate to your amazon server and replace the layer in the web map with a URL that starts with https.

Unfortunately, the locate button cannot be displayed when the map tour is embedded. This is because we never want a viewer to see a Story Map that has a locate button that will always return an error. When an story map is embedded in another page, there is no reliable way for our application to determine if the top-level webpage, and all nested pages have a secure connection (https). If at any point, the secure connection is broken, the browser will reject our request for location due to security reason. For this reason, we disable the locate button when the app is embedded.

I just tested your app and was able to upload two photo (near Portland, ME so you can "reject" them). One used the guest login and the other I logged in with ArcGIS. The app will automatically reject low resolution photos. Are the photos at least 700px on the smallest side?

Yes, all you have to do is make sure the URL starts with https not http. If it is http, just add an "s" after the "p." You should see a green lock in the URL bar if you are using the correct URL. Once you have the app loaded over https, you can share the URL or click any of the share buttons in the app.

I just looked through our code and it appears the change in Chrome happened in December 2016 and we were able to roll out a fix in the December release of ArcGIS Online. ArcGIS Portal releases occur a couple month after their ArcGIS counterparts and will include previous version's template updates. The fix will automatically be applied the next time your administrator updates your version of Portal. Alternatively, if you need the fix immediately, you can ask your portal administrator replace the Map Tour template files with the most recent version from our github account: http://links.esri.com/storymaps/map_tour_template_zip

Did you download and host the version of the map tour on your own server? There was a change in Chrome a few months ago that required us to change our drag-and-drop code. If you did, you will just need to download the latest version of the code to get a fix.

Does it respond it you double click on it? Sometime touch devices will count a click or tap as a mouseover or hover event. This usually happens if the CSS has a hover selector or their is also a mouseover event for desktop that has not been disabled. You could look into using a gesture library for better event recognition on touch devices. This one might be easy to include since you already have access to the dojo library: dojox.gesture — The Dojo Toolkit - Reference Guide.

Ralf, the shortlist app recommends using photos that are no larger than 700px to make sure they load quickly even on slower internet connection. Because the shortlist is a responsive app, the photos will change size based on the size and aspect ratio of a viewers browser and will resize to best fill the space in the side panel. Users with large or high pixel density monitors will automatically get a larger photo; there is nothing you need to do.

Looks like this one still works: http://links.esri.com/storymaps/numbered_marker_symbols.

Hi Julie, did you make sure to download the developer download and follow all these instruction: GitHub - Esri/playlist-storytelling-template-js: A storytelling template that organizes point data sets from a CSV file …? The error you're getting appears that you never ran "bundle install" or that you have not installed ruby or the bundle installer appropriately. If you're on windows, you should also make sure you are using a command line program that provides access to the ruby commands. You should be able to run "ruby -v" and "bundle -v" to see the version numbers of each program installed.

Patrick, A public user account will work well for students who will create a limited number of story maps and create simple maps in ArcGIS Online. Most story maps are compatible with a public account; the one exception is the Story Map Crowdsource app because it requires a hosted feature service to collect contributions. Have a educational organization account on ArcGIS Online will provide some more features that you may find helpful. Besides enabling feature service use, you can also use a educational account to run spatial analysis tools, have more storage and limit sharing with just a classroom. Esri provides free organizational accounts for educational use. You can request one here: Esri | Free online mapping for your school.
