Bug:Recorded Audio Muted

[E13v3n_1111]

I have an iPhone 6 Plus, music studio 2.6.5, and I just downloaded IOS 10.0.2. After downloading the new update for the iPhone, I'm unable to hear my tracks I record. It's not the polyphony, the song only has one midi piano track and four audio tracks that will not play. I know that it acknowledges my recording because it shows up as if it were hearing me. It's doing the same thing as if I were to have a polyphony problem, but it's not that. I've loved this app since the day I got it, I would really appreciate if you could fix this. I already miss making my music. Thank you.
