That was the problem. Once I gave OpenTasks the permissions manually (didn’t ask for that), DAVX asked me for permission as well. Would be cool if that would be a less confusing process…
The Tasks (referred to as OpenTasks, but called Tasks according to f-droid) app which is recommended to manage tasks doesn’t provide a way to add task lists which have been created after the server has been added in DAVDroid. It’d be nice to mention this limitation in DAVDroid.
