I'm having a recurring issue with an app I am developing. I have several ListViews (with custom ViewCells) with ItemSource bound to ObservableCollections within view models. In every case, when the ListView initially loads, it remains completely blank until it is tapped, at which point all the items load. When changing the source (for example when filtering the items), again there is no change until the screen is tapped.
I would post images showing this but I "have to be around for a little while longer before you can post links".
Both the model and ViewModel implement INotifyPropertyChanged. Is there anything that might be causing this to occur? This issue is specific to Android; I'm not experiencing this on iOS.
