Meta XR SDK - Thumbstick scroll not working on UI

Is the thumbstick scroll broken in the Meta XR SDK?
It used to work fine in the old OVR Integration Kit, but ever since I switched to the newer SDKs it hasn't worked since.
I've been holding out since beginning of this year for a fix, but it is still broken for me with v68. I have tried making several test projects to try and make it work, but and it always fails.
It works fine with the XR Interaction Toolkit from Unity, but as soon as i switch back to Meta XR SDK then the thumbstick scroll won't work, only the drag scroll works.

Has anyone else had this experience?
Or even better, does anyone know a fix for it?

I have not assigned any input actions, it seems importing the OVRRigComprehensive gives us all the mappings, but perhaps that is not the case? Do we need to setup up default input actions ourselves?
