This event is working on iOS and Android, but does not seem to be working on UWP. Tested on a Win 10 VM and also a simulator and the event never fires. No touch screen, only using a mouse.
Is it meant to work on UWP, or do we need to get access to this another way?
Holding event is touch only on all platforms. If you want to have enable holding for mouse then you have to add logic directly to mouse events to the view you are working with.
