I have been using Foobar2000 Mobile on my iPhone 6S Plus for a while successfully and want to move to TuneFusion for syncing content. After syncing for about 10 minutes on a large library Foobar crashes and the sync fails. I can't restart Foobar as it crashes on the startup screen. Things I have tried:

1. Shutdown and restart phone. Cannot start Foobar
2. Remove and reinstall Foobar - works fine until partially synced and crashes again stuffing the app. Reinstall again.
3. Had success with small sync (5 albums) but can't do a larger sync (40 albums) without crashing.
