I created an app with ArcGIS Experience Builder and it works quite well at the Experience Builder plattform. Then I switched to ArcGIS Hub, used drag & drop to add a new app and selected the app from the content-library. The app is loaded since two ours without completing the processes. There are just three blue bars moving up and down (see screenshot). I repeated the steps several times, always getting the never ending loop of the three blue bars. Your advise is much appreciated. Thank you.
