Description
Building the XRI 3.3.0 Starter Assets package sample for Quest in Unity 6000.3.0b5 throws roughly a dozen each of these two warnings: _REFLECTION_PROBE_BLENDING, and _REFLECTION_PROBE_BOX_PROJECTION.  

See Logs and Links below for the complete messages for one of each of these warnings.  These warnings do not occur using Unity 6000.0.58f2. 

This warning is thought to arise from this file in the attached project: /Users/dennisd/Documents/Unity_Projects/6000.3/XRI_330/XRI_URP/Assets/Samples/XR Interaction Toolkit/3.3.0/Starter Assets/Shaders/interactable.shadergraph

Reproduction steps
1. Uncompress XRI_URP.zip, and open the project using using Unity 6000.3.0b5. 

2. Build Profiles > Meta Quest > Switch Platform. 

3. Build Profiles > Build. 

Expected behaviour
APK builds without Console warnings.

Actual behavior
Roughly a dozen warnings similar to the two warnings below appear in Console.
