That is my thought as well, and Nothing X has no idea how to read or check updates as there is ZERO loading spinning as I check for updates, just shows my version flat.
Edit: attaching images here shortly

Additionally, if you see, I have in parenthesis calling out the date/time it was updated from factory, which is another sign to me, this is not a proper firmware version and I am stuck with nothing but a return, unfortunately. Or maybe they all show that way on the 3?
Either way, Nothing X won’t search updates and stays still when clicking the update option. I mean not sure how else to interpret this but bad software and a one-off hopefully? But it does not search for updates to my knowledge like an update should, like a token or pathway is broken from my version on my watch, to the Nothing X application version I have.
