Input Touch not firing when using "New Editor Window (PIE)" in UE4.26.2

I’ve got a problem when using “Use Mouse for Touch” functionnality.

Touch events are only working when testing the game in “Selected Viewport” mode. but in PIE Mode It doesn’t work.

The joystikcs works fine, but my game is a touch like interaction, joysticks no need for them, the touch does work on the widgets but doesn’t work on the map itself, even though it does work in Selected Viewport Mode.

Help?
