Hi Michał! Just to make sure I understand: the issue is gone after a reboot, right? And the logs, they were collected after the reboot, I guess? I'm asking because at least the "Snap.Connections.txt" looks fine at a first sight.

Do you happen to have the journal logs for that boot? Better if complete, or if you are afraid that there might be sensiive information, "journalctl -b <boot-id> -u snapd" should be good enough.

Hi @mardy - yes, exactly, I rebooted after change 5 and things are fine since.

I can share my state.json, if you suggest how to strip it of sensitive data (I dropped serials and macaroons, but in case there's more?).
