"Visual Studio for Mac" Code Completion Barely Working In Xamarin.Android

Question

I'm using "Visual Studio for Mac" and the code completion for Xamarin.Android is terrible. Here's a screenshot of me trying to add some menu code to my MainActivity.cs. When I finish typing everything, the compiler does not complain but the lack of suggestions is troubing.

Is there a way to "turn on" code completion?

Same problem using Xamarin Forms on 19 Nov 2017 in 7.2.2.

The fix for me was deleting <solution_name>.userprefs and re-opening Xamarin Studio
as suggested in this question
