Project Version Management
When running the game build on an Android environment, check the APK version installed in the device and the one registered in the BACKND Console.
If there is no version registered on the BACKND Console, the APK version on the Android environment cannot be checked, and the game cannot be run.

Refer to the Version Management page to register a version in the BACKND Console for gameplay.
The CheckVersionStatus() method in the project's BackndServerState.cs file compares the running client version with the registered version to determine the playability.
Refer to Project Version Lookup for more details on the function.
