According to the directions for setting up Web AppBuilder Developer, you don't need an appID with an IWA Portal:
But when I try to set up WAB Dev on our portal, it still asks for one:
The instructions for setting up WAB Dev make it sound like it should skip this step and go directly to the login page. We still have some users using their built in Portal logins as we haven't moved everyone over yet, but I'm not sure that should make a difference. Someone I talked to at the DevSummit said there's supposed to be a property in the signininfo.json that recognizes it's web tier, but I don't have that file unless I create an appID, which I'm not supposed to need and round and round it goes. Any help is much appreciated.
We have Portal for ArcGIS 10.6.1 and I'm trying to install the latest WAB 2.12.
Thanks for your time,
