Most PPC Scope users have their initial data imported within 24 hours of connecting their Amazon MWS credentials.
There are many reasons why the initial data load could take extra time.
We request the data from Amazon immediately after setup, but they are slow to return it.
Larger accounts with lots of advertising campaigns or accounts with very large search term reports can take a little longer
If you have a new ad account and have not had at least one campaign running for a couple of weeks then there will be nothing for Amazon to send us.
If after 24 hours you are still seeing the spinning wheel then reach out to our friendly support team by opening a new conversation using the blue icon to the bottom right of any page and they will investigate this for you.
