UMG Media Gallery

Hi Everynone,
I tried today your way, and it works very nice with the button.
I setup the scrollbox with the same size of the images contained in it (1920x1080), and when I use the button with the offset on 1920, the scrool stop exactly on my image.
But my problem is the touch control. I tried to use it without button and doesn’t work, because after swiping the scroll come back as if there was a magnet.

I tried to set up somenthing like this:

But doesn’t work also. What I will setup?
(I have in My Player Controller all my blueprint with the touch and mouse control)

Thanks again for your help and time!
