Open App Versions for the first time
Open App Versions from the admin settings, see the list of installed apps, and confirm the App Store source is reachable.
Roll back an app to a previous version
Pick an earlier version of an installed app from the App Store and replace the current install.
Install versions from GitHub or Codeberg
Bind an installed app to a GitHub or Codeberg repository so App Versions installs releases from there — for apps that release faster on a forge, or that are not in the App Store at all.
