Unity Core Assets 4.4.0 examples not visible inside Headset

[gameshire]

Hello!
I started a new Unity project and imported Unity Core Assets 4.4.0. After importing I enabled XR in Player settings. The example scenes run fine without errors, but the application is only shown on the monitor but not the HMD (Oculus Rift CV1). Head tracking and hand tracking both seem fine, but somehow the application does not play in the HMD.
It is working completely fine with the previous examples in Unity Core Assets 4.3.4 but not with the new Leap Rig in 4.4.0

Should some other settings be changed?

Software versions:
Oculus App version 1.37.0.245188
Leap Motion 4.0.0+52173
EDIT: Unity 2018.3.4f1

Stuff I have ensured:
1. Enabling support for XR in Player Settings in Unity
2. Enabling unknown apps in Oculus
3. Building and running the application separately (same problem, app works fine on monitor but not shown in headset)

What version of Unity are you using?

Sorry, I seem to have missed the most crucial bit . Please see my edit in the original post above. Thanks!

Hey can anyone please give me pointers as to why this might be happening? What else could I try to make this work? No errors come up during this, so I don't have much to go on with.
I had searched around for anyone else encountering similar problems but haven't found any situation like this.

Ok, so stuff is working now.
I tried opening up a new Unity project to try and pin down the problem. Followed the following steps in order:
1. Enabling XR support in the new project.
2. Tried out the SampleScene of the new Unity project, I noticed it working with the headset now.
3. Imported the Leap Motion Core Assets 4.4.0 package
4. Opened up an Example scene provided in the Core/Examples and it was somehow working!
For some reason the packages related to XR support were not imported properly I think (maybe due to improper order of steps). Anyway all is well that ends well. Off to work! Thanks for all the help everyone.

PS: Please tell me if I need to mark the thread as Solved or something, I'm new here.

As far as I know, LeapMotion can be worked on ‘Multipass’ VR mode which means you can not use LWRP or HDRP with LeapMotion as they support ‘Singlepass’ VR mode only.
If you use built-in render pipeline, select ‘Multipass’ mode on XR settings and try. But the performance would be bad.

It is possible with few tweaks. For more info see: https://forums.leapmotion.com/t/hands-fly-away-with-lightweight-rendering-pipeline-in-unity/7110/22
