If you no longer want to see another player's chat, follow these steps:
  1. Tap on the player's character to select them and open the Friendship menu.
  2. In the Friendship menu, scroll to find the chat icon, a speech bubble with an ellipsis (...).
  3. Tap on the icon with a lock in the chat bubble above the chat icon to mute or unmute that player's chat. There will be a menu prompt to confirm you wish to mute the player.
We are currently aware of a UI issue obscuring the mute button as shown below, but it does not impact the functionality of the button itself.
Muting a player will only prevent you from seeing their chat, but they can continue to see yours.

You can undo this setting by repeating the steps above.
