Scrollrect Clamp Not Working

Hi All,
I’m trying to implement a vertical scrollrect using the clamped movement type but for some reason it will not move when the type is set to clamp. If I set it to unrestricted or elastic it works but I need to clamp the contents to the view to prevent it from infinitely scrolling or snapping back to the middle.
I have tried to disable the inertia and change with the options, but clamp just does not work.
My Unity Version is 2020.3.11f1.

Turns out the content size was set to full size and the height needed to be set to a specified amount of space.

Thanks, works for me.
