Object in hand anchor resets to init position

So I created a scene, added in the OVRCameraRig, attached a cube to each left/right hand anchor and built the scene to headset and everything worked fine.
moving the controllers, i could see my cube moved along with the controller movement.

today, when i rebuilt the scene to the headset, this functionality mysteriously broke.
moving both controller, i could only see 1 cube move while the other remains idle at start position.
i touch a button on the other controller and immediately the cube from that controller follows while the cube on the other control's position reset.

both controllers are tracking as i see them move from the guardian boundaries..

why is this happening? why did the behavior suddenly changed and i dont see both cubes move with controller? how to fix this?

Using Unity 2018.3.12 with Oculus Quest and latest version of the integration.

 

I saw some reports about bugs with some quest games with the latest firmware update which appear to be related to forthcoming Oculus Go emulation. I believe the fix was adding a property to the Android Manifest file

 

The property was
<uses-feature android:name="android.hardware.vr.headtracking" android:required="true" android:version="1"/> as noted here: https://www.reddit.com/r/OculusQuest/comments/chjpu5/fix_for_sideloadedhomebrew_apps_and_games_with/
