Steps to reproduce:

I sync my calendar via Nextcloud (version 27.1.2) This works quite nice in most cases but there is one situation where Thunderbird doesn't sync my calendar entries reproducible, when I create the calendar entry with the default calendar app from Samsung on my smartphone.

Steps to reproduce:

  1. Create a calendar entry with the default calendar app from my Samsung smartphone
  2. Check if it was synced to Nextcloud, the Nextcloud calendar shows the new entry correctly
  3. Force a calendar sync on Thunderbird

Actual results:

Nothing, the event doesn't show up at Thunderbird.

There is no relevant error message in the console of the developer tools.

Expected results:

Thunderbird shows the new event in the calendar.

If I modify the calendar entry with Nextcloud, e.g. change the reminder, Thunderbird can sync the entry just fine. I downloaded the calendar before and after I modified it.

This is how the entry looks at Nextcloud directly after it was created with my Samsung smartphone (Thunderbird doesn't sync it):

This is how it looks like after I changed the reminder from 10 minutes to 11 minutes (now Thunderbird can sync it):
