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.

Details:

Newtonsoft.Json.JsonSerializationException: Unexpected end when reading JSON. Path '', line 1, position 1.

For the past 2 weeks or so, I've found OneClander is suddenly really slow at synchronising (to Google calendar) - making any new addition or change to an entry triggers a painfully slow sync. If I try to do anything else while that is happening (or act a normal, forgetting it's running slowly!), the app crashes to desktop.

Annoying, since it's been fine for a couple of years. I did email support a few days ago but zero response.

OneCalendar was working fine. Then I updated to OS 14.5 and lost the widget. Can I get the widget back?

Event created by the Google Calendar from "Events from Gmail" do not show up.

Hello 

Just wondering if there is a way of syncing Samsung's default calendar? I cannot see it in the adding profiles option.

one calendar is very slow and crashing, why is this happening? what are you doing to fix this considering it is a widespread problem? Why are you not responding to previous requests for help on this matter?

I have a webcal calendar which works well in google calendar, that doesn't get updated, each time a sync is done, another set of appointments is added in paralell. Erasing the account erases all appearances.

I'm sometimes getting a synchronization error if I decline an event: RequestType: POST RequestUrl: https://graph.microsoft.com/v1.0/me/events/AAMkADhmMjM5ZmVmLWZiNTgtNDcwMi05ZTU3LWZjOTJiNzI4OGVmNgFRAAgI3OmHplHAAEYAAAAAhddX0hORW0ir00tBC71axAcAlFbnrSgN8kiFXAX0LYvuUAAAAAABDQAA72K-L9WTT0mM70fgBnp9mAAGWi5eKAAAEA%3D%3D/decline RequestData: {"sendResponse":true} ResponseData: {"error":{"code":"ErrorInvalidRequest","message":"Your request can't be completed. The meeting organizer hasn't requested a response."}}

When creating an entry there is no longer an option to make it a series. Windows 10 with all current updates.

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. I didn't change anything and my Android app ist still working with the same connection settings. My Let's encrypt cert is valid and working... Is it maybe a bug of the new version?
