Oculus Quest 1 not generating rec.upipelinecache file

Hello, I'm trying to implement ue4's native PSO system into my project. Right now it won't cache and generate the rec.upipelinecache file nor it's associated folder CollectedPSOs. Even when I manually create the CollectedPSOs folder.

I've followed UE4's own tutorials for Gathering PSO Data and Enabling PSO Caching. The only deviations have been the Gathering PSO Data's step 5, where I select Android and Android_ASTC instead of Android and Android_ETC1.


However nothing I've tried so far has resulted in the rec.upipelinecache file generating in my Quest's folders. Is there something these two tutorials neglected to mention or do I need something else to set-up the PSO caching? Is it even possible on the Oculus Quest?

Here are the links to the aforementioned tutorial pages:

Did you ever resolve this? 


I'm running into this issue as well on my Quest 2 (I'm doing the Oculus VR Production for Unreal Engine tutorial, and am in the PSO Cache System section


The CollectedPSOs folder is empty, where I should see "UE4+Dev+Documentation-CL-328342-Darts_GLSL_ES3_1_ANDRO_UPIPELINECACHE File".


It's interesting that the CollectedPSOs folder was at least generated (as opposed to other UE4 builds where I hadn't attempted).

It appears someone down in the comments at this tutorial had the same issue, only it spontaneously resolved:
