If you have your game logged in with Facebook then you can delete and redownload madden mobile and it should work just fine. You will get your same team back as long as you use the same Facebook account.
My Madden Mobile was working fine on yesterday but went to play it on this morning and it continues to say scouting New players. Why won't it load and when is the auction going to be repaired great game but the small problems are a major headache to gamers.
Have you had any feedback? I just lost my team for the 2nd time I'm thinking... The Muthead forum suggested I remove and reinstate the app. Lost all and as I don't have Facebook I had to restart. Have a cracking team and invested much time... Not happy EA
