Crashes with long mp3s – Notetracks - a collaborative platform to review, record and share your music ideas. Review

I bought this to make notes on long mp3 files. So far I haven’t been able to open them. The app crashes. I have tried closing and restarting the app as well as the iPad air. I have tried twice to contact the developer. I have not heard from them. With a short piece the app worked decently.
