Nativized Blueprint helps in Win64 but not ASTC

Greetings,

I have one main Blueprint in my project that does a BOATLOAD of math on every tick.
I Nativized the Blueprint and built to Win64. Pretty much doubled my frame rate. Yay!

However, our final product is meant for the Oculus Go.
When I Package the project for ASTC, I don’t get any errors, and the product works,
except I get none of the frame rate benefits I experience on the Windows build.

Is it possible Android ASTC is ignoring the Nativize Plugin and still using the Blueprint version of my creation?

Has anyone else had issues with Nativizing not working in ASTC?
The benefits on the Windows build are quite noticeable. Really need that same increase on Android.

Any ideas?
