Suddenly the majority of my applications have failed to display any operational layers upon loading the Web App Builder application. It was just big white side bar upon load. Therefore, I had to go in and edit it to remove the layer list widget and then add it back. Save and it's good to go. Unfortunately, it now has a group layer issue (multiple drop downs) when there is only a single layer and that is not needed. The web map the app is based on literally has one layer with no dropdowns, so I am not sure why the multiple drop downs in the app.
Example: ArcGIS Web Application
- everyone of these layers (except last) is a SINGLE layer, not a group layer. Why am I getting drop downs? Why is this happening? Thank you.
