I am this same issue in my 24 hour game. I will not be able to move and I will try again in an hour or and it will let me. I hope it does not kill my game.
Won't let me move pieces to desired place

How are you playing? Web or app?

Web on my phone. I have tried a couple of browsers with the same result. Mashing my finger harder on my phone screen worked on my last move. Maybe that is it.

You might try clearing your browser cache.

The game won't allow me to move my pawn to queen it.
It's not your turn to move. Wait until your opponent gets out of check, and then you can queen your pawn.

It does this even if it is my turn.
What exactly happens when you try?

I click to move it and the notification sounds all work, but then the piece just returns to it's original spot
What mobile browser are you using? Maybe something is interfering with the promotion dialog.
Gentlemen,
that was silly!
I appreciate you kindly indicated the (visible) reason, I shd have looked better. All the best, and I'll be more careful.
