Thanks for your kind advice. I have opened an issue on the nextcloud github page:
Can't access shared collections
on my Radicale server I set up 2 users (userA userB). They additional use a shared calendar. so my directory structure looks like:
each user has permission to it’s own directory and to the shared folder.
Everything works fine from InfCloud and Thunderbird with Lightning and SoGo connector.
Whatever I enter into DAVdroid will only show the entry of the user that try to connect.
The shared Calender is never shown.
Thanks for support
