The red Claim victory bar started appering during the game, every time during the opponents turn (though he was playing normally and finished the game). This happened to me a few weeks aho, but thought it had been solved.
Here is the game: Coolmanq vs StanislavSD: Queen's Pawn Game: Chigorin Variation • lichess.org
Thanks for reporting this, @testarlite 
That “Claim Victory” bar showing up mid-game seems to be a visual glitch that sometimes reappears after firmware or app updates.
It usually doesn’t affect gameplay or rating — the match can still continue until completion.
You can also email info@bryghtlabs.com with your board details and a screenshot if you’d like the team to check it directly.
I’ll keep an eye out to see if others are noticing it again after the latest release.
(Linking your example game helps a lot — thanks for including it!)
Thanks @testarlite , I’ve reviewed the logs for this game. Your ChessUp2 received a notification when StanislavSD left for a few seconds, but did not seem to receive the opposite notice indicating when they had returned. Not certain yet if this is a board firmware or server issue - I’ve reached out to Lichess for some clarification around this aspect of their API, and how we should handle it.
