Hi,
I have created a webmap and used this map in an ExB. I use a list widget to give an overview of polygons in a feature layer.
After I have reordered the feature layers in the webmap, made groups in the webmap, the list widget gives the error "Data is inaccessible". This means I have to go through the list widget(s) to reconnect the data.

This also is occurring with the Edit widget
