App used to be perfect. – Tempo SlowMo - BPM Slow Downer Review

This app used to be my go-to music player. I had unlocked all the features and was putting use to the pitch and tempo changer. Now, when you add a song, the pitch changer feature locks up and you can only change the tempo of the song. Can this app be fixed please it’s the only app on iTunes that allows you to add music from your Apple Music library and edit pitch/tempo.
