Mobile Presence Broken on Note 10 and ST 1.7 40-21

ST Classic after Nov 15 update - Presence no longer works, icons missing, app crashes

Beginning around the Nov 15 update, the mobile presence sensor stopped triggering my routines. This feature worked flawlessly for years until now. Also noticed all my device icons disappeared and when I try to add them back, there are no icons to choose from. The icon lists are empty. The app crashes intermittently almost immediately after I open it. Go to Google Play and read the latest reviews. Everybody is complaining about the presence no longer working. I already tried removing/reinstalling my phone from the app, and removed/reinstalled the app itself. Reprogrammed the routines, double checked the geofence was accurate, etc. to no avail.
