one way only sync

[DoctorSubtilis]

With davx on my Moto g32, Android 13, I can sync tasks only from smartphone to remote caldav server, and not viceversa. Calendar sync is ok (bi-directional), but tasks sync no: if I want change a task I have to modifiy it on the smartphone. Or I can delete it from smartphone, and then (only in that case) I can sync from my PC (remote server).
But the syncro should be bi-directional even for tasks, and not only for calendar events, shouldn't be?

Yes. Which tasks app do you use? Which local changes are not synchronized? Did you force synchronization in DAVx5?

Can you please provide steps to reproduce the problem?

1. I use jtk board (and recently I reported a bug there)
2. not even one is synced from local
3. what do you men with "force synchronization in DAVx5"? What should I do?

[rfc2822]

Did you select the correct list in jtx Board?

Works here without problems.

I have activated a verbose debugging, and I saw an certificate autentication (security) problem. I have accepted the certificate.
Maybe this was the problem. I will do some further attempts.

Unfortunately: just the first time, but now changes from PC to smartphone are not accepted.
