When i use function: `addAnchorPointUsingHitTestResultAsync(hitTest);` The anchor is added as expected, but when i use function: `addAnchorAtPositionAndRotationAsync(position);` i got an error: Uncaught (in promise) DOMException: Anchor creation failed. Where is my mistake? This PG [Babylon.js Playground](https://playground.babylonjs.com/#HYK4HC) with first function. This PG [https://playground.babylonjs.com/#HYK4HC#1](https://playground.babylonjs.com/#HYK4HC#1) with second (wrong) function. ---

For some reason adding anchors in unbound space it not supported. change it to local-floor and you get the results you expect: [WEBXR | Babylon.js Playground](https://playground.babylonjs.com/#HYK4HC#9) ---

Hi, When I run this in immersive mode (using WebXR in chrome) I get an error “the required feature ‘anchors’ is not supported” do you have any idea why? Thank you, Tali ---

@RaananW is the king of VR, and the more I read V/X/A R questions, the more I think to dive in to help him more than pinging him 🙂 ---

Hi Tali, I assume you mean chrome on android? Have you turned on the webxr incubations flag in chrome://flags? ---

I’m using Chrome on my PC and have WebXR set to Samsung Galaxy S8+(AR) in WebXR in the Babylon Playground. Yes I have the incubation flags turned on. ---

no PC/desktop browser has the anchors feature turned on. You will have to use mobile. ---

Oh that makes a lot of sense! Do you have recommendations for how to use Babylon on mobile? I have an iPhone. Would it work to run it on a HoloLens as well? Thank you! ---

The only devices supporting anchors currently are Android devices with the latest chrome. IPhone doesn’t support WebXR (thanks apple), and hololens doesn’t have all ar features yet as far as I know. Latest chrome on android supports anchors, plane detection, hit tests. ---

Thanks, when I open [WebXR - Samples](https://immersive-web.github.io/webxr-samples/) on chrome or chrome canary I get AR and VR support detected. But when I open any of the demos they don’t work. I’m trying to get the anchor demo [Anchors](https://immersive-web.github.io/webxr-samples/anchors.html) in particular. Any idea why? Using latest chrome and have incubation flag enabled.
