Why do I need this plugin if there is a free GooglePlayLicenseVerification repo?

The GooglePlayLicenseVerification repo was released back in 2012 but didn't receive any major updates since then. First of all, it doesn't have a defined API. You have to adapt the CheckLVLButton.cs for your project, which is a manual and error-prone process.

I've been a user of this repo for three years, but time and time again, new problems appeared. All issues listed below are not hypothetical; I encountered all of them in production with both of my Google Play Pass games:

1. System.IO.Directory.Delete() can throw an exception:
   System.IO.IOException: Directory not empty at System.IO.FileSystem.RemoveDirectoryInternal (System.IO.DirectoryInfo directory, System.Boolean recursive, System.Boolean throwOnTopLevelDirectoryNotFound)
2. Process() callback is called from the background thread. Executing any Unity Engine code (except a few APIs like Debug.Log) from the background thread will produce an exception.
3. Doesn't support Unity 2019.1 or newer.

The 'Google Play License Check' plugin solves all the above issues and provides a clean and simple API. To verify how simple it is, please check the forum thread.
