5 years ago It looks like we're running into a AOT issue:
{System.ExecutionEngineException: Attempting to JIT compile method '(wrapper delegate-invoke) System.Nullable1<int> <Module>:invoke_callvirt_Nullable1_SendChatMessageInput (Services.Chat.SendChatMessageInput)' while running in aot-only mode. See https://docs.microsoft.com/xamarin/ios/internals/limitations for more information.
Could you please attach a sample project, as we'll likely need it to run down this bug.
