I'm completly lost on this issue. I have a crash that seems to be only happening on the iPhone 4. This is a line of business app and not supporting the iPhone 4 isn't an option. I have a View with a list that allows users to inspect parts of a room. If they open the detail from the list, then go back the app crashes. I haven't been able to make any sense of the stack trace. I can reproduce this bug with Xamarin Forms 1.5, 2.0 and the latest pre release. Any help would be greatly appreciated.
