Hello there, I made a few plays on Android 11 via Chrome ad/or BGA app, but in both cases I am unable to send anything in chat. I have no "Send" button, not in the chat windows nor in the keyboard. That's annoying, to be honest.
What can it be? Bug or my settings problem? Any solution?

press enter twice and it should send the message!

Damm, I was trying to hit Enter, but maybe I was acting too slow. It worked.
Thanks!
