Minecraft Support is experiencing extremely high volumes of requests right now and we're working 24/7 to get caught up. Do we have help? You bet, we just added forty new people to our team. Thanks for your patience, we're going as fast as we can to get them in and helping out!

@MojangSupport I have an iPhone 6 and have had this problem since I bought the game. It won't let me play with friends or invite them to my games, even though I have the option activated when I start the game, it disappears and crashes.
