I cleared cache partician, only and haven't seen any issues, since I forced the update, last Friday, but I'm not daily driving it. It doesn't have a SIM. It's my backup / alarm clock.
I had planned on using it daily, but had an issue getting all of my Google calendar events to cross from the Note 9 to the S9. The events wouldn't even go to my Google calendar on the web. I had been trickiest trouble shooting this issue on and off for a couple months.
I FINALLY found the answer in a gourmet community forum and it was NOT the recommended solution.
The fix was changing which calendar was selected in ONE new event, to change the default. Apparently, Google updated the app, changing this default to "MY CALENDAR", which seems to be only on the phone and not sent or to the web or other devices instead of the "EVENTS" calendar. Changing this in one new event, changes the default for future events, it seems.
