I've set this up in NC 18 and migrated to NC 19 and 20, no issues – so from an "admin that is just using this to solve a specific issue" perspective, there's nothing that needs to be changed except the max version to support NC >18. For my instances it currently is the only app left that needs an "activate untested app" :/

Please also check if you may set max version to NC 21. I had very little issues migrating my test instance to NC 21 Beta 1 :)

It would be great to have this App supported in NC 19.

@sunjam please change subject to "Support for Nextcloud >18" since NC21 already has a release candidate.

have anybody running this on NC22?

Yes, works fine for me on NC 22 on arch with all up-to-date versions.
