I am currently using the OneCalendar app and have encountered an issue regarding calendar permissions when using multiple calendars under a single CalDAV account.

In my setup, I have one CalDAV account with two calendars. One calendar has "modify" permission, while the other has "none" permission(read only). However, I have noticed that when these two calendars are present under the same account, both calendars become unable to be modified, despite one of them having the "modify" permission.

It appears that the presence of a calendar with "none" permission is overriding the "modify" permission of the other calendar, causing both to

After the latest cumulative update for Windows 11 ver. 23H2 2024 05 (KB5037771), One Calendar stopped displaying calendar events on the lock screen. Fix please.

cpanel is caldav server - onecalendar been working well on android  and windows 10 computers with my cpanel calendar for 6 months+. About 2 weeks ago all onecalendars developed sync error - I think cpanel version may have updated recently to version 120, not sure if this is the issue - caldav and calendar working OK on Thunderbird - no sync error. have checked the caldav url at the cpanel end.

If I remove account from onecalendar and re add this is what happens

and there is now no data in the onecalendar. I cant make sense of the error.

When I try to sync on windows app it fails with one error. I have two google calendars registered in the app and only one of them seems to sync anything. Even if I uncheck syncing of both calendars, the error still occurs, so it must be a problem with the app and not the calendar.

I am running OneCalendar on my Windows10 PC and my Android phone with different calendars (even one CalDav calendar) perfectly since one year. But since two weeks, my Windows App gives an error "Supporting to secure channel there was an error: NO RESPONSE" (see message below) for my CalDav calendar and I am not able to get the calendar.
