I downloaded LocalLayer Widget 2.8(from GitHub link). I added one dynamic layer. I have one dynamic service added. Then I configured this widget to "Open this Widget automatically when the app starts" by clicking on the bottom-left circle on the widget.
Now when I run the app, everything is fine and my freeway layer is loaded on top of Basemap.
Only problem is the 3 vertical loading bar is spinning forever. The problem is still there even when I re-created a new app with only this widget configured. (Please see attached screen)
If I do not turn on the automatic open, there is no spinning bars. But I have to click on the widget to turn on the freeway layer.
