I have the following setup:
- MacOS native calendar connected via CalDAV to Nextcloud 25+
- Shared calendar in Nextcloud with another user
The problem is, that the other user keeps receiving a notification about me updating given calendar event, even though I never updated it and the event is just as it was.
Once I disconnected the MacOS from Nextcloud, it stopped, thus I suspect that MacOS is performing a no-change update when it syncs.
I found a mention of another user having similar issue. But I believe the problem is not global, as there would be more fuss about this - how can I check what’s exactly wrong with my setup, why is it happening and how do I fix this?
