What is happening? Tried to upgrade from 21.11 like I did with two other devices before …

When updating from one version to the other, then you do not touch the stateVersion ever. Instead you add the new channel, run a channel update and after that you rebuild/switch.

The stateVersion does not get bumped unless you know exactly why you do it.
