TouchPinch not working properly on computer with touchscreen

I’ve got a custom camera script and i have a UserInputService:TouchPinch(). It gets the touchPositions but on roblox (from the microsoft store) it only shows 1 touchPosition:


(It is supposed to show number,number number,number not number,number nil)

This works on Iphones

Is this an existing issue with Roblox or what?

I want to find out the number of touches in a touchpinch. Can someone help me do that on roblox from the windows store?
