When the ListView has more items, it could be vertically scrolled, however, there is no UI for vertical scrollbar on Android.  The same can be observed with RadTreeView control.

Images loaded from memory stream behave strange - on iOS they don’t load immediately, only after list is scrolled and after that they start resizing and reordering randomly when scrolling; on UWP they load on initialization but have same problem with reordering.

The control listen for changed to re-filter, so when any property is updated, there is a side effect on iOS - the entry used for editing loses focus.

This can be reproduced in the SDK examples ->ListView -> Gestures -> CellSwipeEvents. 
1. Change the content of the items so that they have uneven height
2. Scroll down 
3. Delete an item by swiping
-> Expected result : The items re-arrange correctly
-> Actual result : The item is deleted but the ListView is scrolled up when the UI is updated

When reordering items in the ListView sometimes the user might want the item to go to the end of a long list. It is not possible, because the ListView does not scroll while dragging the item.

Release 2019.2.708 (R2 2019 minor release)

When RadListView is placed inside a TabViewItem content of the RadTabView control,  it does not preserve its SelectedItem, scroll position and expanded items (if it is grouped).

The LoadOnDemandItemTemplate's HorizontalOptions setting is ignored on Android, it will always be left aligned.

See this screenshot for comparison of 3 target platforms side-by-side:

The DataTemplate is as follows:
        <Grid BackgroundColor="Red" 
             <Label FontSize="24"
                         Text="Load more items"
                         TextColor="Black" />

It seems the scroll position is calculated incorrectly in this case.

With the previous release (2018.3.1) displaying many items (10000+) with groups and sorting took less than a second. With the latest release (2019.1.1) the time is increased to several seconds on the same device.

When swiping a cell, the swipe content of the cell will be shown if the swipe threshold is reached.  On iOS, the swipe content of another cell can be shown immediately by swiping another cell (which is an expected behaviour).  However on Android, when the user swipes another cell, the swipe content of the other cell isn't shown (while the swipe content of the first cell becomes hidden).  The user has to swipe the other cell again to show the swipe content.
