Moving tasks is not working

[MAWSpitau]

### Steps to reproduce 1. make a task in tasks with due-date 2. go to calendar and move the task from one day to the other 3. it looks like the task moved 4. refreshing the page or move to tasks shows, that the task is not moved ### Expected behaviour - The task should get a new due-dates ### Actual behaviour - The tasks date stays what it was. ### Calendar app **Calendar app version:** 2.2.0 **CalDAV-clients used:** not necessary for ths bug ### Client configuration **Browser:** firefox 87.0 **Operating system:** Manjaro - GNU/Linux ### Server configuration I am on a shared hoster: https://www.hetzner.com/de/storage/storage-share/nx10 So I cannot tell anything about it.

Please provide browser console logs and nextcloud.log.

As far as I know, tasks are read-only in the Calendar.

Hey, thanks for the answers. But these are contrary. Is it basically possible to move tasks in the Calendar or not? If not, I do not know, why I should give you some logs.

this used to work in some older nextcloud version.

I would also like to see this working. I'm not sure if it worked in an older version or not but it'd help my workflow a lot. Thanks!!
