@rfc2822 Thanks a lot for your quick reply! You were right: Having edited the affected entry in the nextcloud GUI, subsequent edits one the mobile phone synced without a problem.
Thanks again! Christoph
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.
… and please keep us up-to-date about what you have received
What ever happened with aCalendar’s Tasks module here?
