I can't play it – FMA Battle Review

I have had the game for three days and I can't even play it. The app always says it's under maintenance and try again shortly. I have tried plenty of times and it is bugging me, I'm only 12 like seriously I wanna play it but it won't even work. If you guys fix this I will probably give it 5 stars because I am a true FMA and FMAB fan.
