Did you send the debug info to firstname.lastname@example.org? I have checked the mailbox but didn’t see anything related.
I have split this thread because the other thread was about tasks and specifically the
COMPLETED property, whereas this thread seems to be about events.
Can you please provide exact steps to reproduce, the complete (anonymized) VEVENT with all properties, DAVdroid debug info and maybe verbose DAVdroid logs etc as described in [READ BEFORE POSTING] What’s required to diagnose a problem?
The VEVENT you have provided looks good and I’m quire sure that your problem comes from other properties which have been omitted in your excerpt. I would have to reproduce the problem with the full VEVENT to have a look at that. Especially, I suspect that this might be a problem with the
DTSTAMP property, and maybe not even related to Thunderbird, but to another client which has created the original event, because everything works with Thunderbird here.
