AR example shows an error message

[hsujj]

I try the AR example link and click “Start AR” :
https://threejs.org/examples/?q=webxr#webxr_ar_cones

I saw a warning message :

THREE.WebGLRenderer: Can’t change size while VR device is presenting.
WebGLRender.setSize @three.moudle.js:25726
onWindowResize @webxr_ar_cones.html:80

Is this a problem ?

Demo Start AR not working in Android Chrome but ok in Samsung browser

I installed google ar service to my Samsung Galaxy S20 FE 5G phone(Android 11). The AR portion of three.js webXR demo example shows nothing after clicking “Start AR” button in Android Chrome (version 87.0.4280.141) . VR demo example works in Chrome. But the “Start AR” and “Enter VR” functions both work fine in Samsung browser (version 16.0.2.19) in the same phone. What is the problem? How to fix it ? This is the AR example link: https://threejs.org/examples/?q=webxr#webxr_ar_cones
