F-Droid 1.19.0 with Auto Updates now marked as "suggested"

On Android 12 or later, apps will be autoupdated after the first install or first update, no root, no unlocking, no PrivExt needed. Older apps that can’t be updated will feature a banner explaining why.

Most old versions of the apps are not build to support that, and you'll have to manually update each of those apps at least once (after they have been built with support for it). When checking most apps at the moment a banner appears showing how the app does not support automatic updates (yet?)

1.19.1 did not work directly for me either.

Installing 1.19.0 worked fine, then I was able to upgrade to 1.19.1 normally in app.

Same here
