Decals not showing up in ASTC build

Hello,

I have been trying to build a VR experience to Android ASTC and am having some issues getting decals to show up. The Decal shows up in the editor and in play mode but when it builds and is deployed on the PicoGoblin VR headset it does not show up. The sound plays so i think the decal is there but is not rendering. I have referred to this forum but have had no luck in resolving the issue. Any ideas on what may be wrong?
