Whats wrong?

Ive been playing (and enjoying) this game for a long time. I just upgraded from an iPhone 4s to a 6 (iOS 8.3) and suddenly the volume is either full blast or physically muted. I tried deleting and reloading the app, and the first time it seemed to work for a while. Then it cropped up again and wont resolve. I hope it gets fixed soon - it seems like my day is not complete without my Hearts Premium fix.

UPDATE: The sound volume issue has apparently been resolved and all is well again.
