If you no longer want to track Facebook or Amazon ads, you can do that on the My Data page.
To disconnect your Facebook and/or AMS data:
Go to your My Data page
Click either the “Disconnect Facebook” and/or the “Disconnect Amazon Ads” button.
Enter your Publishwide account password when prompted
Click the button that says “Disconnect Facebook/Amazon Ads.”
A message will appear at the bottom of the screen, telling you that the ad account you selected has been disconnected.
NOTE: You will not be able to retrieve any daily data from Amazon ads beyond the last 90 days if you disconnect and reconnect your AMS data. This is due to a limitation imposed by Amazon itself. Your Facebook ads data will not have this limitation.
