Pros: You can play Advance server with it's new features, heroes etc.. Cons: You can't bind your account with social media platforms. If you deleted this mlbb beta app, you can no longer use your account in advance server. Can't recharge, can't exchange vanguard coins on the recharge channel. Late updates unlike on original advance server which they released the update more often. It's not worth your time
