Workaround

iOS:

1. When I remove the Gesture Recognizer it is working
2. When I keep the Gesture Recognizer and set the SelectedItem that is bound to the CollectionView via command, it is working as well

For me it seems that the Gesture Recognizer is blocking the SelectedItem Binding from View to ViewModel

Android: n/a
