That setting has been removed from the general settings in browser (in the app it is still at the general settings also). If you open a game and go to the settings from there, it can be found (both in browser and in app). It is weird that the setting has been changed by itself, because I have always used setting "stay on this game". I leave this thread here if anyone else is wondering this setting changing by itself.
And about conditional moves:
Mobile
Conditional moves are currently only available on the Andriod Chess.com app.

It has been this way for a very long time. When are conditional moves coming to iOS apps?
At daily chess, how can I stay at current game after I make a move? In the app I find setting for that and it stays in the game, but in the browser it doesn’t stay anymore and I cannot find a setting for that 🧐
I’m using browser and app, because in the browser one can make conditional moves. I haven’t been able to find conditional moves in the app.
