Virtual Hands and Hand Tracking Missing in Unity Play Mode via Quest Link

Hi,

I’m experiencing an issue where hand tracking does not work through Quest Link in Play Mode within the Unity Editor — virtual hands do not appear. My setup includes Unity [6000.0.33f1], Meta XR All-in-One SDK [74.0.1], OpenXR Plugin [1.14.2], and Quest 2 (system version [v74.1020]). Hand tracking works when built as an APK on the Quest 2 but fails via Quest Link, despite being enabled in the headset settings.

The Unity console shows warnings like `XR_ERROR_HANDLE_INVALID` from `xrGetHandMeshFB` and `xrGetSkeleton2` (full list below), suggesting Quest Link isn’t passing hand tracking data correctly. 

```

```

Can you confirm if Quest Link fully supports hand tracking in this scenario? Are there specific Oculus app or firmware settings (e.g., experimental features) required to enable it?

Thank you,
