Okay, so I just tested this and I haven’t been able to get it to work.
I started by testing with an existing app. I reconfigured it as Jeff described and then tried logging in, using Google authentication. After the authentication process, I just got the spinning loading icon and the app never actually loaded.
I tried again by creating a new app from scratch…
- Configured User Profiles
- Upgraded the app to Private Pro
- Set Privacy as Limit to Emails in sheet
- In the whitelist sheet, I just added a single row in the email column in the form
@domain.com
- Published the app, and tried logging in using an account from that domain
Same result. After authenticating, I just got the spinning loader and the app never finished loading.
So at the very least, I would advise testing this yourself before relying on it.
@Jeff_Hager - any ideas? Have you ever tested/verified this behaviour yourself?
Update: I also tested using the PIN method. After entering the email address, the “Sending Pin” button appears, but it gets stuck there, and the PIN never arrives.
