Once I have downloaded it, played it for a bit and gone off the app, whenever I go back onto the app, it shows the background to the home screen (the nether) and no options come up for me to play. It is just the background. So i am having to keep unistalling it and redownloading it. Which is frustrating. It's making me lose interest in the game and I don't want to get rid of it because it's a extraordinary game and I don't want to lose that. Thank you for listening.
