I got the sample project from Apple’s official documentation (https://developer.apple.com/documentation/gamekit/creating_real-time_games/). That sample project is a simple real-time game where two players are immediately aware of the actions each other takes. I figured out that one of the player's phone keeps buzzing when the voice chat is turned on. Suppose we have player A and player B. When the Voice Chat is activated, I noticed that player A can clearly hear player B's voice, but player B cannot hear anything except for their own voice, which can be heard by player A. Occasionally, this situation can switch. When a player is unable to hear anything, they only hear a constant beeping sound, even though their voice can still be heard by others. What happen? Anyone figured out how to solve this?
