everytime i try to battle a friend online it instantly crashes does anyone know how to fix this
its a bit glitchy. usually freeze.
btw would you like to try to battle?
Online battling in-game is still buggy to the extent that only 1v1 battles are possible and crashes will happen very often for no reason.
Reason being any kind of switching(including switching in a pokemon after the previous one faints) causes the game to get stuck. In addition, the following also cause the same: Any switching moves that cause switching like U-turn, Volt switch, Whirlwind, Roar, etc.; leech seed, and custom moves. If a critical hit occurs, that causes the game to be stuck on waiting as well.
