I have a similar problem. I play Minecraft Pocket Edition in IOS. When I opened the game a note popping up. It says "There is an error with your account. You will be unable to use the marketplace. Error number -9". I can't enter the marketplace. Also I can't play multiplayer. When I invite my friend, my invitations doesn't pop up in my friend's game. She can't see me in friends tab. I can't join her world too. She can send me invite also I see her in friend tab but when I accept her invite nothing is happen. A few minutes later the world start to loading but then it says "unable to connect to world". Same thing is happen in friends tab. The featured servers not shown. It says" coming soon". So I added a server and tried join but it said "unable to connect to world" a few seconds later it said " invalid identity public key". My friend and I are connected to Xbox. I don't understand what is the problem. Please deal with this.
