I recently set up nextcloud-aio and also installed dav_push. In DAVx5 i connected ntfy which works already with other apps. In DAVx5 i also did a refresh in the account, CalDAV and CardDAV views but it is not showing any of Server advertises Push support nor Push support: Subscribed. Normal sync works in DAVx5. How do i debug this either in DAVx5 or Nextcloud (cli)? Thank you for your help!
