Reflection Probe Box Projection in URP Not Working on Oculus Quest

Box Projection with a Reflection Probe using URP on the Oculus Quest 2 isn't working for me on my builds. I have Box Projection enabled on the reflection probe and in the Universal Render Pipeline Asset, but in my builds, the reflections act as if Box Projection is not enabled. Is Box Projection fully supported for URP on the Quest?

I'm using Unity 2021.2.14f1.
