Pre moves

Are pre moves for USchess tournaments disabled? Mine don't work. And when down on time it's really hard to move. 

Are they enabled for normal games?

If premoves are enabled in your settings, they are available in all live games

That’s correct.

SOLVED: You need to change your settings on both mobile and desktop to enable premoves. Or at least, change/update your settings when you are playing here in this club. 
Thanks for your help.
