Closing this because this seems to be a Thunderbird-related problem and not a DAVdroid issue. If you think this is a DAVdroid-related issue, please post again here and I’ll re-open.
problem syncing tasks with acalendar+ and davdroid
I am using acalendar+ and moved from caldav-sync to davdroid. Everythings works, I see my calendar and task entries from owncloud. But if I create a new task in acalendar+ and press synchronize (yes I prefer manual synchronizing), only calendar entries are synced. Tasks are only synced if I press “synchronize tasks” in the account settings menu or in the OpenTask App. With caldav-sync syncing of tasks directly in acalendar+ works, why not with davdroid?
Please ask aCalendar+ support directly.

What ever happened with aCalendar’s Tasks module here?
