Hi, this never worked in XF, so is not really a bug, more a enhancement. Normally user's use the click event.
Marking this to be look further as an enhancement.
Can you please provide a scenario you need this also to help us out.

Thanks.

It's working with images, content views etc.
It has a problem with button only. I'm willing to have double tap.
TapGestureRecognizer has a property for this. (NumberOfRequiredTap). It's also useful for right click on UWP.

I'm facing the same issue with ImageButton too (XF 3.4)
