When the ItemSwipeStartingEventArgs.Cancel property is set to true:
Android: NullPointerException
UWP: cell content disappears

If EndItemSwipe() is called inside the ItemSwiping event handler, the ItemSwiping event continues to occur on iOS until the user physically ends the swipe gesture.

On Android the header items are taking too much space and are invisible using GroupHeaderTemplate.

Available in minor release 2017.2.0602. It will also be available in the R2 2017 SP release.

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.

Reproducible on Android 6.0  or higher.

When setting HorizontalItemSpacing or VerticalItemSpacing to the layout, the item spacing appears to be applied twice to the item. 
When setting BackgroundColor to the ItemStyle the background leaks beyond the boundaries of the item.

If ListView has PressedItemStyle defined and the end user holds onto any control, such as Label, for example, placed outside ListView, the PressedItemStyle is applied to all items. Can only be reproduced on Android.

Currently, the behaviors differ in Android/iOS and UWP. In UWP you can have an empty collection and the LoadOnDemand will trigger when you open the page with the ListView, in iOS/Android you need to have some items in the collection for the LoadOnDemand event to trigger.
