Failed to poll initial positon, no head position found

Hello, 
I created a blank project in Unity 6000.0.37f1 and dowloaded the latest version of Meta All in One (v72) and Meta Avatars(v33).

i just created a blank scene and added all the building blocks necessary for tests the new avatars (camera rig, virtual hands, passthrough, auto matchmaking and avatars).

the project is correctly connected to an app on the store and the avatar spawn correctly, but after the spawn i got this two error:

-[ovrAvatar2] OvrAvatarBodyTrackingMode.Standalone is deprecated, please use OvrAvatarBodyTrackingMode.None instead and set the InputTrackingProvider, InputControlProvider, and HandTrackingProvider properties of the OvrAvatarInputManagerBehavior MonoBehavior on the OvrAvatarEntity prefab/instance.

this one as the debug say i just changed the tracking in None and it look fixed.

-Failed to poll initial positon, no head position found
UnityEngine.Debug:LogError (object)
Oculus.Avatar2.MecanimLegsAnimationController:PollInitialPosition () (at Assets/Samples/Meta Avatars SDK/33.0.0/Sample Scenes/Scripts/LegsNetworkLoopback/MecanimLegsAnimationController.cs:624)
Oculus.Avatar2.MecanimLegsAnimationController:UpdateState () (at Assets/Samples/Meta Avatars SDK/33.0.0/Sample Scenes/Scripts/LegsNetworkLoopback/MecanimLegsAnimationController.cs:280)
Oculus.Avatar2.MecanimLegsAnimationController:Update () (at Assets/Samples/Meta Avatars SDK/33.0.0/Sample Scenes/Scripts/LegsNetworkLoopback/MecanimLegsAnimationController.cs:238)

i lost two days for understand what is happening but still i didn't understand the problem.

can you guys help me?

    I guess this is the problem:

    "Caution: The Building Blocks currently do not support the Avatars SDK v33 or later yet, so please stick to v31 for now. The issue is that the avatar is not moving with the OVR Rig."

    I had the same problem... Replacing the "AvatarSdkManagerStyle2Meta" and the "LipSyncInput" objects with the ones provided in the MirrorScene Sample (Samples\Meta Avatars SDK\33.0.0\Sample Scenes\Scenes\MirrorScene) fixed the issue for me👍
