Oculus 1.35 + LWRP + UsePerEyeCameras = Broken?

Is anyone able to get multiple eye cameras working in LWRP?  Inside the editor positional tracking appears to work, but in the headset it hangs on a "Loading..." screen.  Disabling the LWRP profile does not have this problem.

Oculus 1.35, Unity 2018.3.9f1.  Have tried multiple projects installing OVR from the asset store and also package manager.

Any help much appreciated thank you.
