I tried sending a friend request & direct challenge and nothing happened. The other player did the same & nothing happened. I physically watched them through a discord livestream send me a direct challenge & friend request not a **** thing happened on my screen. Arena has been out long enough to know about this continuous issue & it's about time it's been fixed. I've been playing & dropping $20 per set for the last 4-5 sets, get you're **** together or the next thing I drop is this game.
