Forum:Help please!!!

Ever since the new reebro was introduced I can't sign in to my game! My son was able to sign on to his game but as soon as I switch it to mine it blinks out. Basically when it stars loading the color fills the title and as soon as it would normally go to air island it "blinks" and I'm back at my home screen. Any advice? I don't even know how to contact support to tell them what's happening. Thanks in advance :')
