I just recently had one of my Web Maps stop loading. After doing some trouble shooting I realized that it was the Living Atlas layer "Live Stream Gauges" by Esri. Taking that layer out of the map allows the web map to be shown publicly. However, when I add the layer and then configure my web application to allow subscriber access. Either the map will not load, or I get a message that the layer can not be displayed. When I tried to create a brand new application such as a Dashboard instead of a Web Map, I get a message the layer does not allow content to be enabled.
Did something change with this layer?
