I’ve maybe misunderstood the 4.0.7 release note but I thought it was written that when you won against a bot you’d have the crown displayed on the list of bots on the embedded screen but this is not the case after upgrading to beta 4.1.0. Did I misunderstood the feature or is it a bug ? Note that I didn’t have the chance to install 4.0.7, I directly switched from 4.0.5 (or was it 4) to 4.1.0, which may be the explanation.
Also, I do see username for logging out of chesscom as announced but not on lichess
Chess.com crowns should start appearing after the next server restart.
If you signed in to Lichess before the update to add usernames to the sign-out buttons, the board may not know your username yet. Please try entering the Lichess flow and going back to Settings→SignOut. This should now show your Lichess username.
