update and issue resolution:
Howdy,
After several support contacts, eventually Google acknowledged and worked on, and resolved the issue (see official Google G Suite Tech support trouble ticket emails below).
There may be some delay, and/or calendar cache cleaning needing to be done:
Here's the official Google support responses is that you may need to still :
-disable the Google calendar account from within Apple's system preferences->Internet accounts, quit Calendar.app, then purge the Apple calendar cache files, then re-enable the Google Calendar account:
To purge the calendar cache files.
I've written up a basic procedure to safely do so:
- go to calendar.app, go to settings, go to accounts, uncheck the calendar to disable, then quit the calendar application.
- then, go to your User Library folder ( ~/library/calendars/ folder),
(you can easily lookup how to do this if you don't know how to find it)
- then, delete all items with the name "Cache" in it such as:
Calendar Cache-shm
Calendar Cache
Calendar Cache-wal
- go back to calendar.app, launch/run it, then, go to settings, go to accounts, check the calendar to re-enable your Google calendar account
- Then finally, you may wish to also click CMD-R to refresh calendar data and wait for enough time for all data to re-sync
