When I launch the "Attachment viewer" template and select any map, the map window just stays empty in the configurator after I have selected a web map as the content to show. It shows only the items of the app configurator however, nothing of the map. I tried this in Firefox and Chrome and with different web maps...is there a bug in the template? I have an older Attachment Viewer Web App that still works, but when I try to edit this app, it's the same: map window remains all empty, only configuration items visible (see attached screenshot).
Can someone try this out please? Can you reproduce this?
Thanks!
