LineRenderers and TextMesh in URP w/Oculus Quest (Unity 2019.3.6f1)

I am having trouble with LineRenderers and TextMesh components displaying in my Oculus Quest while using URP. Playing in the Editor, they work/look fine. When I run my app in the Oculus Quest, they aren't there however.

LineRenderer:
I am using a custom shader for my LineRenderer Material that merely draws a colored line, found below. I am aware of XRLineRenderer but it doesn't seem to support URP based on github issues and forum posts.
EDIT: Even switching my material to use an Universal Render Pipeline/Unlit shader (practically what I am doing), causes the LineRenderers to be visible when Playing on my laptop, and non-existent on the Quest:

Code (CSharp):

1.  
2. Shader "Unlit/ConstLines"
3. {
4.  
5.     Properties{
6.         _Color("Main Color (A=Opacity)", Color) = (1,1,1,1)
7.     }
8.  
9.         SubShader{
10.  
11.             Tags {
12.                 "Queue" = "Transparent+2"
13.                 "IgnoreProjector" = "True"
14.                 "RenderType" = "Transparent"
15.                 "RenderPipeline" = "UniversalPipeline"
16.             }
17.  
18.             Pass {
19.  
20.             ZWrite Off Lighting OFF
21.             Blend SrcAlpha OneMinusSrcAlpha
22.  
23.             CGPROGRAM
24.             #pragma vertex vert
25.             #pragma fragment frag
26.             #include "UnityCG.cginc"
27.  
28.             fixed4 _Color;
29.  
30.             struct fragInput {
31.                 float4 pos : SV_POSITION;
32.             };
33.  
34.             fragInput vert(float4 pos : POSITION) {
35.                 fragInput o;
36.  
37.                 o.pos = UnityObjectToClipPos(pos);
38.  
39.                 return o;
40.             }
41.  
42.             fixed4 frag(fragInput v) : SV_Target{
43.                 return _Color;
44.             }
45.  
46.             ENDCG
47.             }
48.     }
49. }

TextMesh:
This uses the 'Gui/3D Text Shader' which most likely isn't URP compliant. So that probably explains why it doesn't show. Does TextMeshPro support URP? I am not sure, based again on forum posts (https://stackoverflow.com/questions/59359507/textmesh-pro-not-compatible-with-lwrp). What approach are people taking to display 3D text in VR URP?

Thanks for any help. I can provide more information if necessary!

 

False alarm...original developer had absolute paths to the underlying data for our linerenderers and text.
