Can't Drag GLTF With OrbitControl In AR

I am having issues dragging a GLTF in AR on mobile. The OrbitControl works correctly but I can’t drag / scale the model. I have applied the different fixes from various other posts but haven’t been able to get it working. I can drag the model around in the “preview” window but once I click the AR button I can no longer move it. I believe I have all of the necessary WebXR Chrome flags enabled.

Any help would be greatly appreciated.
