@pacsni It sounds like you’re still having the issue you reported in, e.g. , Guide: Elixir App v1 to v2 migration (It was easy) - #16 by pacsni?
i.e. you’re trying fly machine update with definite config changes, and getting back Error no config changes found instead of a diff and a request to confirm?
Can you confirm that with the latest stable flyctl, running fly m update --restart always <machine-id> doesn’t work?
