Yes! Problem is solved for me, too.
Disabeling the CyanogenMod Privacy Guard was the solution.
Thank you all!
Is this possible to do? I tried to do it but it shows error - server not able to find.
I created a Joplin folder in disroot, shared and copied the link and pasted it in configuration of Joplin with my email and password… I thought it would work.
Sorry… I’m noob I don’t know exactly what I’m doing.
For syncing Nextcloud (or other CalDAV) tasks with DAVdroid, you need OpenTasks, see here: https://www.davdroid.com/manual/introduction/#c215
Does that help?
