Used to love it till iOS 9

I used to love this app, I bought it for my iPhone 4S and again when I changed my iTunes account for my iPhone 6S and also purchased for my iPad Air2. The issue came with iOS 9, now when I "mix" my song and transfer it. It comes out at 2x the speed..... so it sounds like Alvin and the Chipmunks!! This is infuriating, I used to use this as a poor mans studio. No solution has been offered at all. Happens with both Mac and Windows
