Sorry for pulling this up again, but it was the most relevant thread I could find yet.
I have similar issue. I am fresh user of GOS on Pixel8pro
I have used acalendar+ before to maintain and sync Google calendars with the family and love the functiinality.
I am now searching solutions for 2 issues:
I would like to continue with acalendar pro, but I could not manage to implement and sync it to the existing Google calendars. Sync request is already send out by acalendar and received and confirmed within Google account - but the Gcal and its entriss does not appear now in acalendar in GOS.
Is there may be any setting missing I need to do?
2nd issue or target:
Of course I want to change over from G calendar AS basis to an alternative solution giving the same functionality with shared family calendars and best with an local stored calendar which can be syncronized.
But a online calendar service allowing me to sync with acalendar (which is only a interface to maintain Android calendar as basis) would be perfect too.
Many thanks for your help and suggestions in advance!
