Some normal maps/textures consistently appearing black on Android client

[chedsapp (ched)]

My game (RoSim [EARLY ACCESS] - Roblox) has an asphalt texture that renders correctly on PC and MacOS clients, but on the Android client it appears black.

Reproduction

Create a MaterialVariant with the following properties and assign it to a part.
Color - rbxassetid://12920950409
Normal - rbxassetid://14976075460

Expected behavior

How its supposed to look

[iiostream]

Appears the normal map was invalid for this case

Thanks,
