pressing player name no longer brings up menu to add friend report player block
It does that on the website. 
It works on the Android app too. (At least in the beta version.)

I sometimes wonder if it's a function of the opponent disabling chat. But that should ONLY disable the chat link in the menu. I should still be able to report the opponent, add friend, and follow. This happens about 30-50% of the time I'd estimate.
Hello, still having this problem, around 30% of the time. Perhaps it's just opponent disabling chat?
