How can I kill this evil thing?
This is probably not the place to do it but I figured it would be where I could find someone who fixed it.
So I had a very nasty behaviour of my exchange work calendar which I synced into my Nextcloud calendar, and it would automatically cancel and recreate all events, which would resend invitations to attendees. It was very unprofessional, to say the least.
After months of this, I finally figured out that the culprit was the calendar auto-backup in the Android Nextcloud client. Turned it off, and my problems went away. Maybe you have something similar going on?
Don’t use the Google Calendar app to sync your CalDav stuff
I don’t use Google Calendar, I use Samsung’s.
Samsung calendar accesses Google calendar
Get one from F-Droid, and sync with Dav5X
