I have a little xamarin ios app and these couple of days I'm facing this issue. I'm working on VS 2017 and unfortunately I haven't got that "Check updates" portion in Tools -> Xamarin menu. Besides, the automatic update notification is not popping. So I don't know how to get the latest Xamarin.iOS 10.8 update. I'm facing this issue in 2017, because in VS 2015, that I was working earlier , the "Check updates" were working fine.
Please, can anyone tell me , how can I update the Xamarin.iOS version ? Any other alternative ways to install those updates ?
