Why 14 days?
Google Play's closed-testing requirement involves at least 12 real testers staying opted in for 14 continuous days before we can request production access. We'd appreciate your staying opted in for at least 14 days, ideally 16, and trying the app on multiple occasions. Approval isn't automatic.
