Select your app.
You can now click the "Save" and then the "Add for Review" button at the top right.

Afterwards, click "Submit to App Review" in the popup that comes up on the side of the screen. This might take a moment to load.

It should then say "Waiting for Review".

Now you just need to wait a bit. It usually takes less than 2 days for the app to be reviewed by Apple. In most cases Apple will find some minor issue and reject the app at first. In that case, please contact us and we will help you resolve the issue so Apple accepts the app.
