Unity android build showing static object.....

Aloha, Im just trying a simple scene with a AR Camera (has key code etc in P-Settings) and a game object set in front of the ar-camera. I have Track device Pose checked, and Tracking Mode set to Positional....
On the android (several devices same isue) the camera starts, has vuforia logo in corner, the gameobject (capsule ) is right there, but when the phone/tablet is turned the capsule is static on the screen as the video background moves.....

Unity version 2018.3.2f1 EDITED: Updated to 2018.3.3f1 no change, same problem
Vuforia 8.0.10

been playing with this for a few days... I dont think the device is being seen for changes in orintation....

Id like to try vuforia version 7.5 or so but cant find it to revert...

anyting im missing?

Thanks in advance for any and all responses
