In the Nextcloud that is included with my /e/ account I have setup several combined calendars/tasklists. Tasks can be seen in the calendar on the web interface. However they don’t appear in Tasks app or Calendar app on my /e/ Fairphone 3. The phone synchronises with my /e/ account through DavX5. The calendars synchronise OK, it’s just the Tasks that don’t. And the Tasks app on the phone doesn’t show the new calendars/tasklists that DavX5 has, only the default ‘Personal’ one.
