Doesn’t work – Slow Down Music Trainer Review

I just purchased this app based on the advice of my kid’s music teacher. I’ve seen it work, but it doesn’t for me. Getting the "problem calculating song length” error. I don’t use iTunes Match or iCloud on this particular device, and all the songs are natively synched. The songs play just fine in the native music player app. I’m running IOS 9.2.1 which is the latest available for iPad Air (my device). The last time this app has been updated is almost 3 years ago. If it doesn’t work for modern devices or IOS versions, it should be noted in the description. Otherwise, it should be pulled from sale. Andy Davidson, please fix the app, or refund the money to all those who have purchased the non-working app!
