Audio Editor - Music Cutter

The thing is that it will work perfectly on my iPhone but when I got it on my iPad none of my songs would import to the app

At first I loved this app, but then it got to the point where it asked me if I wanted to pay $0.99 to upgrade since it wouldn’t allow me to use it if I didn’t pay, so I did and I ended up getting charged $5.94 which I’m completely upset about and would like a refund of some sort because the app still won’t let me use any of its functions even after I paid. If you could please reply to this and get it fixed as soon as possible I would really appreciate it because this is unacceptable.

Just the app I need to make a mix of songs I like! However, my only question is how do I upgrade to unlimited? I wanna get rid of the ads. Other than that, it’s a phenomenal app that is both easy to use and gets the job done!
