Struggling to get body tracking initialised for movement SDK examples

Hi there,

I'm currently looking at examples in the Meta XR Movement SDK (Running the MovementBody scene), and I cannot get body tracking to successfully initialise. I get the following warning which I presume is the source of the issues. I get the same warning running the advanced examples in the SDK example scenes:

[OVRBody] Failed to start body tracking with joint set FullBody.

UnityEngine.Debug:LogWarning (object)

OVRBody:StartBodyTracking () (at ./Library/PackageCache/com.meta.xr.sdk.core@e6e7a2c46b82/Scripts/Movement/OVRBody.cs:161)

OVRBody:OnEnable () (at ./Library/PackageCache/com.meta.xr.sdk.core@e6e7a2c46b82/Scripts/Movement/OVRBody.cs:130)

I get a different warning running when looking at the Meta Xr Interaction SDK Example Scenes (BodyPoseDetectionExamples). I'll say that I've tried the configuration for just upper body also:

Global joint set is invalid. Ensure that there is an OVRBody instance that is active an enabled with a valid joint set

UnityEngine.Debug:LogError (object)

OVRPlugin:GetSkeleton2 (OVRPlugin/SkeletonType,OVRPlugin/Skeleton2&) (at ./Library/PackageCache/com.meta.xr.sdk.core@e6e7a2c46b82/Scripts/OVRPlugin.cs:9479)

OVRSkeleton:Initialize () (at ./Library/PackageCache/com.meta.xr.sdk.core@e6e7a2c46b82/Scripts/Util/OVRSkeleton.cs:595)

OVRSkeleton:UpdateSkeleton () (at ./Library/PackageCache/com.meta.xr.sdk.core@e6e7a2c46b82/Scripts/Util/OVRSkeleton.cs:857)

OVRSkeleton:Update () (at ./Library/PackageCache/com.meta.xr.sdk.core@e6e7a2c46b82/Scripts/Util/OVRSkeleton.cs:850).

My Hand and Body tracking is enabled in my headset settings, I have developer runtime features turned on. I've screenshotted my settings for each example. I'm using version 83.0.0 of the movement SDK, and 83.0.3 for the interaction SDK. I'm at a bit of a loose end so any advice would be greatly appreciated - thank you!
