Hi a friend of mine is using self hosted nextcloud (All In One 28.0.3) with microsoft office. to syncronise calendars, I installed caldav. the connection works properly but all the calendars show up in the same colors and all the calendars are shown, not possible to hide some of them. any ideas?
Maybe the colors were set before syncing? Try adjusting one to a new color, see if that change is synced. It would be silly, but maybe that’s the case.
