Can anyone help me with this crash? It crashes on start up according to the App Review. It was written in C# using Xamarin iOS. I've tested the app in debug, release, and TestFlight on both iPad and iPhone and haven't been able to replicate the crash. Here's part of the crashlog, I couldn't fit the whole thing in the question. If you need anymore information let me know.
