My Xamarin.Forms app throws exception:
Microsoft.CSharp.Runtime-Binder.RuntimeBinderException: Cannot apply indexing with  to an expression of type "Newtonsoft.Json.Linq.Jobject"
This only happens in the iOS release version installed on device (either by Xamarin on my device, or from Apple Store by customers).
It works fine on Android (same code!), also tested on iOS Simulator, both Debug and Release - works fine.
The code is here (2nd line):
dynamic json = JObject.Parse(message);
long time = (long)(json["timestamp"]);
I am using Newtonsoft.Json 11.0.2 (not the latest)
Any idea? Maybe some release mode optimizer removes something what should not be removed?
