Ahhh okay i overlooked that. I read the title and dismissed it prematurely... Should i close this one as a duplicate?

It's not a duplicate. I just linked these two issues because they are similar to each other and may have the same root cause. If it were a duplicate, I'd close it 🙂

Had the same issue, but it's gone after i switched off and on 'CalDAV sync' button in calendar settings After that davx5 sync have also start working for calendar, but if i call sync inside app (pulling down reload) it shows massage that it's successfully done, but it's actually not.

But i have no this problem on xiaomi (android 10) and realme (android 14) phones
