If your opponent is sending too many emotes and distracting you, you can mute them by following these instructions:

1. Tap the Chat button on the bottom left of the screen.
2. Click the 🚫 button above the top left corner of the panel. The button will change to ✅.

Emotes and messages sent from opponents will be blocked, and you will also be unable to send emotes or messages.
 
Note: To receive and send emotes again, tap the ✅ button.
