App just stopped working – Ringtone Designer Pro 2.0 Review

I would have rated this a 5 the app just closes once I choose a song that I want to edit. After the update on the iPhone X, i was able to creat 2 or 3 ringtones but no it just shuts down. Anything I need to do to fix this? I already tried re-installing the app.
