Eric Schmidt‌, I've been told by my WAB colleagues that the District Lookup widget no longer uses the web map configuration option and is configured directly from the widget itself. Also, just to be clear, the options are still available and can be set in the UX, even though they have the "retired" banner. Perhaps it would have been better to have banners that said "will be retired" at the next release.I beleve that Esri's apps have accounted for this retirement and made adjustments already, except for released apps that are no longer being updated, like the original Collector, which I suppose people could still be using.

Greta Robison‌ No, this retirement shouldn't impact you. These settings were initially used by the original Collector because the app itself didn't allow configuration (I believe). It was a way to expose application level settings from within the map. Any ESRI app that utilized them, will ignore these settings moving forward and do any configuration within the app itself.  Mike ... View more

Kevin MacLeod‌ - Regarding trying out the ArcGIS Platform, there are different ways to do this: Create a public account. You get a certain amount of capability for free. If you decide you like the platform, you can purchase a subscription. At that time, it is possible to use your public account to sign in to your new organization and bring your stuff with you. Sign up for a free trial. You have to navigate our marketing pages for ArcGIS Online, but you can eventually get to this page: ArcGIS Trial | Free 21-Day Trial . After the trial period ends, you can purchase a full subscription. For this option, you can't sign in with an existing public account. Sign up for a free developer account. ArcGIS for Developers . This gets you some capability for free and allows you to experiment and build apps.Pricing | ArcGIS for Developers  If you're working with a school, the school can get a free organizational subscription through the Schools Mapping Software Bundle for Grades K-12 | ArcGIS for Schools . Unfortunately, there isn't a way for students who have graduated to take their stuff with them out of the organization other than the save as method mentioned above, which only works for web maps. Related to wanting multiple people to have control over items, you can create a shared access and update group for members within your organization. This allows anyone in the group to edit the content of the group as if it was theirs. This only works within a single organization, not across organizations. Also, you need to have administrative privileges to create such a group. Members in the group don't need to be administrators. Hope this helps. Mike ... View more

WebGL (Web Graphics Library) is a JavaScript API used to draw 2D and 3D graphics in a web browser. The ArcGIS JavaScript API 3.x and 4.x use WebGL to draw some layers. The short answer You've reached the limit of the number of layers you can add to your map for layers that utilize WebGL. The longer answer The web browser has a limit of about 16 WebGL Contexts and the ArcGIS JavaScript API 3.x, upon which the map viewer is currently built, utilizes one context per layer. A vector tile layer will always utilize a WebGL context and a feature layer may utilize a WebGL context (if editing is disabled, there are no labels and a few other things AND a context is available). To maximize the use of WebGL contexts, I think you can add the vector tile layers first. So, the limit will be 16 vector tile layers. The long term solution When the map viewer is redesigned using the JavaScript 4.x API--which utilizes WebGL contexts differently--you won't encounter this limit. Mike ... View more

We can add a new option to revert layer drawing back to the layer's default style when the styling has been overridden in the map. I've written this up and we'll see if we can get it into the next release. Thanks, Mike ... View more

When you add a map service to a web map, the server that hosts that map service draws an image of the service and returns that image to the client to draw as part of the web map. The labels are part of the image, thus you see them in the web map. When you single out a particular sublayer in your map service, the server no longer draws an image to return to the client. Instead, the server just returns the geometric coordinates of the features in the sublayer. It's now up to the client to draw the geometries based on the returned coordinates. In this scenario, there are no labels.  AGOL does have an ability to draw labels on features, but doesn't have the sophistication of what Desktop can do. Thus, if you need advanced labeling, you'll need to stick with your map service.  Mike ... View more

Chuck, I'll pass along your comments. About a year ago, we did increase the limits for uploading shapefiles. This is from the documentation. Shapefiles—ArcGIS Online Help | ArcGIS  The shapefile must be less than 10 MB in size and have less than 4,000 point features or 2,000 line or polygon features. If the file is too large, generalizing the features will often reduce the overall size and allow the shapefile to be added to the map. If that doesn't work and you have publishing privileges in your organization, it is recommended that you publish shapefiles that exceed these limits as a hosted feature layer. My understanding is that we've kind of reached the limit on the amount of data we can store inside a web map. Storing all of that data inside the map makes the map quite large. That 10 MB shapefile is stored as plain text (JSON) inside the web map and probably yields an even larger map than the original shapefile. That map has to be downloaded to run on the device. Maybe it could perform OK on a PC on a fast internal network, but, for example, downloading that to a mobile device would likely be slow. You say that people download parts of your data. Is your data hosted in AGOL? Are there some common areas or parts of your data that many clients might be interested in using? One idea is to create view layers from a hosted feature layer. View layers can define a subset of features and attributes from the original layer. So, given your source data, you might make several view layers that are subsets that people frequently use.

Hi Chuck, Esri has continually advanced our performance and drawing of hosted layers since the original post in 2012. For example, we've continually evolved how we request large amounts of features from large hosted feature layers, we leverage client side, server side and CDN (Content Delivery Network) caching, and can use WebGL (Web Graphics LIbrary) when drawing layers. Here are a few blog posts I found that describe these enhancements. https://community.esri.com/community/gis/web-gis/arcgisonline/blog/2017/10/17/so-you-want-to-display-a-bazillion-features-on-the-web-a-technical-approach-to-large-feature-datasets  Scalable hosted feature layers in ArcGIS Online: Tile queries and response caching  FeatureLayer rendering: taking advantage of WebGL in 2D  From your post, it seems like you may be loading shapefiles and CSV files directly into web maps. While we have made some performance improvements over the years to increasing the size of shapefiles stored in web maps, we will never be able to get the same level of performance as we do with hosted feature layers. It's just not technically possible. Is there something preventing you from publishing your data as hosted layers? This is really the recommended way to go. Mike ... View more

Sorry, I misunderstood your post. The arcade expression I suggested will not work in HTML.  Mike ... View more
