Once your app has been submitted to the Google Play Store it will be reviewed by a mix of Human and Automated auditors. This review process usually takes between 24 and 48 hours. A few hours after approval your app will appear on the Google Play Store.
Due to the COVID-19 pandemic Google Play review times have increased. New apps can take up to 7 days to be reviewed and approved.
