Every game on game pigeon works except for Cup Pong

Okay, so every game on game pigeon works except for Cup Pong. We can send the games but everytime I click on it, I get to see the person send the first ball, but I can’t see them sending the second ball and the screen freezes right there. It’s been like that since yesterday. Please tell me how I can fix this. Thank you for reading.
