Problem api version ?
Updating from versions 1 and 2 to the latest version 3
In addition to these new features, version 3 also supports all the functionality of previous versions, improving and simplifying how you manage workflows. Starting December 1, 2019, versions 1 and 2 of the Google Play Developer API will no longer be available so you need to update to version 3 ahead of this date.
Migrating to version 3
If you use the Google Play API client libraries (available for Java, Python, and other popular languages), we recommend upgrading to their latest versions, which already support version 3 of the API. In many cases, changing the version of the client library should be all that is necessary. However, you may also need to update specific code references to the version of the API in use - see examples in our samples repository.
Many third-party plugins are already using version 3 of the API. If you use a plugin that does not support version 3 you will need to contact the maintainer. You will start seeing warnings in the Google Play Console in mid-May if we detect that your app is still using version 1 and version 2 endpoints.
