I want to know these devices support the WebXR or not? I tried WebXR sample on Android(Redmi Note 8) and iOS( iPhone X 14.4.2) but it's not working. It's showing a blank screen. But there is the Redmi Note 8 in the table. So the table is a list of the supported devices or it's about unsupported devices? And If I don't install the Google Play Services for AR, the WebXR works fully for AR? If should I install this app to enable the ARcore on my device, what should I do to publish my AR game app? All users should install this app to play my app?
