    Hi, I only had time to look at it yesterday and today, and specifying the OculusAppId and RiftAppId did not solve the problem...

    As we had it running previously without these, I tried a clean full install on another computer, and the VR Preview worked, which made me suspect that it could be a problem with my computer. I therefore uninstalled fully all versions of Unreal, Meta Quest Link, and Android Studio, and fully restarted installing as mentioned in the documentation here

    The good news is that after a clean install the VR Preview now works fine, so there was a problem with my installation. However building to apk then started to fail, with the following error 

    UATHelper: Packaging (Android (ASTC)): Expecting to find a type to be declared in a module rules named 'OculusXRHMD' in 'UE5Rules, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.  This type must derive from the 'ModuleRules' type defined by UnrealBuildTool.
    UATHelper: Packaging (Android (ASTC)): Took 2,19s to run dotnet.exe, ExitCode=8
    UATHelper: Packaging (Android (ASTC)): UnrealBuildTool failed. See log for more details.

    I mention it here in case it can help others, but it looks like the problem came from the fact that I copied the MetaXR and MetaXRPlatform plugins directly into the Plugin folder of UE5_5 (C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\), which used to work for me before. Instead, moving these folders into "C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\Marketplace\ " solved the issue to build to Android apk 

    So in the end, uninstalling everything and restarting from a clean install solved the problem...

Hello there!

Have you made sure you have the OculusAppId setup correctly when enabling the Meta XR Plugin? If you go here, it will show you how to enable this correctly. You can get your OculusAppId if you to the Developer Dashboard, it should be  under Development > API > and then you may generate your App ID token. 

If this doesn't sort out your issue, let me know so we can troubleshoot further!
