Minecraft XBO: Join Game Popup

Um u need to play Minecraft for a few hours then it will popup

I agree with Ragamffn, we have had the same issue with D3 and the reboots. I had tried everything to make sure the xbox runs cooler etc, but it was still doing it. Purposely Qutting the game from the XBO main screen is the only way I have found to stop it.
It could also be the controllers timing out, when they go to sleep, D3 could be trying to popup the "Reconnect XXXXXXX's controller" dialog and since it doesnt have focus it causes a crash which causes the XBO to reboot.

Same thing here. Had to power-cycle (hold down power button for 10s) about 3-4 times before it FINALLY worked. All of our woes with XBO can be traced back to when we first installed Minecraft for XBO. Prior to that, no issues since launch. Since then? Constant
freezing issues--not just with Minecraft but with other games, on start-up, etc.

Make sure you have authorized Minecraft to access your info in the popup. Achievements require it

I had trouble when game was new. Make sure your second controller is sync'd to the Xbox console first. Then login both users before starting the game. Then you should get a popup in game to press the menu button to join.

Good luck!
