Unity 2D Texture array not animating

I'm running a simple test in Unity, playing frames of a 2D texture array over time with a shader. The frames play correctly in Unity editor, and with Oculus Link on device. But when I sideload an apk of the test on device, the fames do not play. I'm wondering if anyone else has experienced this, or does Quest2 not support 2DTextureArray format?
