Well, you are doing nothing wrong, my friend. I have experienced this many times, and chess.com has told me it is a glitch. It is currently being looked at, but it is definitely a glitch. So make sure to report the bug!
Can't play biltz with friend. What are we doing wrong?
Sort:
My friend and I want to play blitz with each other on the App (I'm on Android, he's on iPhone). If I send him a blitz challenge, it sits at the "Searching" screen and he never sees anything. The exact same thing happens if he sends me the challenge. We can send each other messages in the App without any issue though, as well as play non-blitz games. Anybody know what we're doing wrong?
