Hello,
I have an app developed with WAB Dev. Edition with some custom widgets.
Will following scenario work:
Download app from WAB.
Deploy to remote hosting server (the bare bone one, no Portal/Server on it).
Register with AGOL, do all settings etc.
The final result is WAB app on my remote hosting working with data from my AGOL account.
I'm pretty sure it will work, but I like to hear more.
Thanks!
