No "Plus" - Sign anymore

Hi everyone,

anybody know why there is no plus sign anymore to give the opponent more time?

Nice greetings ;)

Short addition. Just played a game and the plus was there. It seems not at all games that the plus is not there.

@marbig01 This only shows up in casual games, not rated ones.

Different opponents have different settings: lichess.org/account/preferences/chess-clock
