Who is App Versions for?
App Versions is admin-only. It changes which versions of Nextcloud apps are installed on the server, so non-admin users do not see it and do not need to.
If you are an administrator on this Nextcloud instance, head over to the Admin guide — that is where the actual walkthroughs live.
If you are a regular user and something is broken in another app ("feature X disappeared after the last update"), let your admin know. With App Versions installed, the fix is often a one-click rollback of that app rather than a wait for the next release.
Status: in development. Once the admin UI lands, this page stays as the pointer it is — the real journeydoc lives in the admin track.
