Xamarin issue with designer in Visual Studio 2015

I have Visual Studio 2015 Update 3, Xamarin 4.2.0.703, Android 7.0 SDK Platform (API 24), Android SDK Tools 25.2.2, Android SDK Build-tools 24.0.3 .

An issue message:

To fix the issue you have to download Android 6.0 SDK Platform (API 23).

Thanks to John Watmuff from stackoverflow.

It’s shame for Xamarin to have an issues like these.
