Apk for the Pico 4 ultra has an error once launched: No Google Play Store Key (No OBB found and no store key)

When attempting to launch my client(.apk) on the Pico 4 Ultra headset, I encounter the error:

“No Google Play Store Key (No OBB found and no store key).”

I have already ensured that the APK is correctly deployed to the headset and that the server is running on the same LAN. I would appreciate any guidance on resolving the error or further steps to successfully connect the client to the dedicated server.

Expected Result:

The client should successfully connect to the dedicated server on the same LAN, and the application should launch without errors.

Actual Result:

The application fails to launch on the headset, showing the error “No Google Play Store Key (No OBB found and no store key).”

Hi Romain, it’s not clear to me whether you’re receiving the error when trying to launch the application, or when connecting to the dedicated server (after having launched the application on device)?

If the latter, how are you establishing the connection w. the dedicated server?

If the former, make sure you are using OnlineSubsystem=Null, and/or disable the Plugin “Online Subsystem GooglePlay”.
