I would really love to know as well. According to the road map they’ve included ARCore 1.7 for the 4.23 release. But we really need ARCore 1.10 if we want to have correctly functioning metallic reflections on Android devices. Currently I’m stuck with a setup where it’s only reflecting from one angle, the rest gets black. If I’m wrong with the reflections please pin point me to the right direction. It works well on iOS with ARKit.
