Workaround In my case, using the MVVM pattern, when the TAB index changes (TabView.SelectedIndex), it is sufficient to update the ItemSource of the ListView by calling OnPropertyChanged(nameof(ListItemSource)), for example, when the ListView is specified as: ItemSource="{Binding ListItemSource}". This allows fixing the bug depicted in the video issue for android too.
