Help :/
 

So I noticed that the new era update had came, so when i tried to update it, a message popped up saying something about a billing error. I signed out of my apple id and back in, still nothing happend. I tried deleting and re-installing the app, and when i tried to download it that message popped back up again. Im just wondering if there is any way i can fix this it does the same thing on my ipad. If you have to update era to play it, im screwed.
