Got signed out of Origin and cant sign back in.

On my IPad I get a undergoing maintenance issue - just prior I seemed to have lost all my friends. It was my IPad that I was playing the game when all the server issues occurred.
Funny thing is I can log on to my iPhone and play the game and still see all my friends.
Hope they can fix this as it seems to be perhaps a corrupted file on the machine you were playing on when the server issues occurred.
