To streamline the add-on discovery experience for users in the G Suite Marketplace, publication of both public and private Drive apps to the Chrome Web Store is deprecated. Chrome extensions continue to be presented in the Chrome Web Store and aren't affected by this change.
Drive app developers were notified of this change with instructions to migrate their Drive app listing to the G Suite Marketplace. If you've already completed this migration process, no further action is necessary.
For future Drive apps, use the G Suite Marketplace publishing process.
