Newest IOS Update 11.0.3 CRASHES APP FATAL ERROR – Musicnotes: Sheet Music Player Review

We use this app EVERY WEEK for our worship ministry. And our iPad updated to the newest IOS (11.0.3) update this week and the app no longer works. When we launch it, the app immediately and repeatedly crashes. Please help! We have invested significant resources to use this tool. Thank you!
