Last 20 messages not showing in the app

Hello Hubitaters. Everything seems to work except trying to view the Last 20 Notification in the app just goes to a blank form with the spinning circle.

  1. This used to work. Possibly it stopped working after a recent update or after I added a 2nd mobile device?
  2. Samsung S10, clearing data and cache, restarting the phone and reinstalling the app don't help.
  3. C8 hub, reboot doesn't help.
  4. The 2nd mobile device is an iPad and viewing the notifications works fine.
  5. The S10 gets notifications fine. It is the viewing of the last 20 in the app that doesn't work.

Thanks!

Ah, Google worked this time. I saw a comment that I should delete and recreate the mobile device on that phone. Success!
