The first question is do you have an organizational subscription to ArcGIS Online? If you have an organization subscription, it is highly unlikely that your data is shared publicly. Only you control access and if you didn't share it publicly, it shouldn't be. When you create an organizational subscription, you define your organization name, which appears as part of the URL. So, you should have something like https://zzz.maps.arcgis.com where zzz is the name you gave your organization. If your URL is simply https://www.arcgis.com then you have a public account. In these free accounts, all sharing of content is shared publicly. However, it's very clear when sharing items that you're sharing with everyone. As to why the usage numbers are high, every time you open a map that contains a layer, the view count is incremented. So it may be that your own testing incremented the counts. The same applies to opening a web application that opens a map, that opens layers, all view counts get incremented. Hope this helps. Mike ... View more

The heat map drawing style doesn't support using custom arcade expressions as the attribute. We don't support it at this time. With hosted feature layers, you can add a new field and use an arcade expression to calculate a value into that field, then use that field as the attribute. However, this may not work in your case as it seems you are using a living atlas layer. Calculate field values—ArcGIS Online Help | ArcGIS  Mike ... View more

You can only create view layers from hosted feature layers, not ArcGIS Server layers. However, if you can publish to your server, you can effectively publish your own second layer to support what you need. Mike ... View more

I've used the template to create my own layer and have no issues changing attribute values based on new list (domain) values. Which layer are you working with? RoadBlocks, RoadDetours or RoadClosures? Which field did you modify the list of (domain)? Did you change how the layer is drawn? Did you change the edit settings to restrict editing actions? Mike ...

I think you might be able to do this another way, by setting up an arcade expression to draw the layer. The features outside of your date range wouldn't be drawn.  When you set the symbology for a layer, in the dropdown that let's you pick a field to symbolize with, you can define an arcade expression. I think using the Now() function of arcade and doing some date calculations with your date field, much like you're doing in SQL, you'd be able to use the Types style to draw features. Features that don't fall into your date range would fall into the 'Other' category of the Types style and wouldn't be drawn. Other Arcade functions that might be useful are the Date, DateAdd and DateDiff functions. Seems like your date values are in days, so you don't need to refresh during a given day. GIven a smaller time interval, you could probably set a refresh interval on the layer to cause it to update, with say dates that are changing by the hour, etc. Here's an expression I wrote that will draw a feature if its date is within the last 24 hours. datediff (now(), $feature.Datef,'hours') < 24 This expression returns True or False, so the drawing will show True or False as the "attribute value". You can return a different value, but this is just a simple example. I them moved the False values to the 'Other' category and turned off drawing of 'Other'. This is simple a drawing filter. The feature is still there, but just not drawn. For example, I was still able to display a popup for the feature if I clicked in the location on the map, even thought the feature wasn't visible.

I'm not familiar with the public notification app, or how it works. As you say, it's ignoring the filter, which leads me to believe that when the app is selecting features within a given radius is accessing the service endpoint directly and bypassing the filter. A filter defined in the web map is stored in the web map, or alternatively can be stored on the layer item if you save the layer from the web map. As long as client apps are accessing through the layer item, they should apply the filter. It is the responsibility of the client app to respect the filter. However, the actual data source of the layer still contains the filtered data and it is accessible.  Here's something you might try and maybe it will work. Instead of applying the filter in the web map, create a view layer of your original layer and set a view definition instead. This actually enforces the filter at the data source level, as if the data isn't there. To create a view layer, go to your layer item. There's a button to 'Create View Layer' Create hosted feature layer views—ArcGIS Online Help | ArcGIS  On the new layer, go to the Visualize tab and in the left panel toolbar click the More Options button (3 dots). You can set a view definition here, which restricts features at the service endpoint.

The issue may be that you're URL is pointing to the item in ArcGIS Online, not the actual PDF File. Here's the URL to a PDF item that I own. This item is shared publicly. With the '/data' appended, it means you want the data stored with the item, which in this case is the actual PDF File. https://www.arcgis.com/sharing/rest/content/items/9501d3d574414943bb0792ee484c5693/data  ...

I was able to assign a string field to NULL. I don't know why it's not working for you. How about calculating it to a single quoted string? ... View more
