"Sync Viewport" not working.

[Charlie-Steer]

I just started messing around with Houdini Engine for Unity, so I could be missing something, but as much as I try I can't get viewport sync to work. Connection between Houdini and Unity seems to work otherwise correctly. The only reaction to the feature I've managed is, with a newly opened Unity window, turning on "Sync Viewport", does teleport the camera in Unity once, although to an incorrect (non-matching) location. Turning the feature on or off afterwards doesn't yield any response. The checkbox does sync correctly (checking or unchecking) on both Unity and Houdini.

Unity 2022.3.5f1
Unity Engine 5.0.0
Houdini 19.5.303
