Unity 6.3 - Meta XR Core license error

Hello all

With the latest release 83.0 and Unity LTS 6.3 I'm getting a package manager error with the Meta XR Core SDK. It is also telling me it's an entitlement package marked with than E. I have a pro license.

[Package Manager] The following packages were not registered because your license doesn't allow it. com.meta.xr.sdk.core@83.0.

Am I the only one getting this and what can be done? Sometimes I'm not getting the error but 99% of the time this is what I get. It happens on other computers and also with a personal edition license. I cannot work on the app because of this. I reverted to Unity LTS 6.0 and there is no problem.

I'm in the same situation with the entire Meta package.

Unity 6000.3.1f1

I encountered the same problem and was unable to install the meta xr package.

81.0.0 seems to install fine, looks a 83.0.0 issue.

Having the same issue. This seems to be an issue with Unity 6.3 specifically, need to wait for Meta/Unity to fix this soon.

In the meanwhile I'd recommend if you want to use SDK 83 revert back to Unity 6.2, and if you are fine with SDK 81 then stick to Unity 6.3.

I just went to Unity Asset Store and added the failing assets to "My Assets", waited a few minutes and refreshed license. Then all worked...

I think they just updated the 83 version to 83.0.1 and it seems to be working on my install. Just reintall the package:
