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.

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

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.

If you have set a custom LoadOndemandItemTemplate when the ListView is in manual LoadOnDemand mode, once you click the Load More button - it gets invisible. Clicking on the area where the button should be is working, though.

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.
