I am currently testing a Xamarin Portable Code application on iOS 12.4.1 after successfully testing the application on the Android platform. Let it be known this is my first app on iOS. I am having an issue whereby when a field gains focus, may it be a picker or an entry field, the drop down or the keyboard does not appear on the device. I am not sure why this is happening as the form renders as expected. Could someone please help me?
