Listview: Grouping by complex properties does not work in (at least) Android
The grouping does not work in Android if you do not use simple type properties to group the items. In UWP everything works fine, in iOS I have not tested the scenario. I added a demo solution to test the issue.

Available in the R2 2018 release.

With the newest Build of the Xamarin Forms Nugets (2017.2.626.3), the error message I get has more details. The problem is, that it is important to implement the NON-GENERIC IComparable interface in the class with is used for grouping in Android.
After implementing the interface, everything is working as expected.
