I play on the chessup v1 game and when I play through the app and play a rated game and choose my color, two times in a row I chose black and was assigned white.
I know at chess.com you cant choose your color for a rated game. But the app lets me do so for lichess. Yet… it doesn’t work. Not sure if that’s a lichess or chessup issue. Probably lichess
I am pretty sure Lichess removed the ability to choose your color on a rated, random challenge. You can still do it with a direct challenge but not with random challenges.
It has been a while now sicne I saw it on Reddit and Lichess. The fact that Chessup app allows you to still do it just means the app has not been updated to match the site.
