Comment 2 for bug 1971987

Ken Vandine replied (https://forum.snapcraft.io/t/gtk-common-themes-out-of-date/29857/8): "It should have updated the tracking channel unless you had perhaps switched to edge or candidate in the past then back to stable."

Sounds like this needs some testing to confirm, since several users don't remember changing the channel.

I'd also suggest that if someone has, there should be an option during the upgrade — similar what happens when there’s a new system config file that conflicts with your modified one.
