Below are a few reasons why auto-import may appear not to be working.
If you’ve just set up auto-import, you may not have confirmations in your in-box that meet your search setting of 1, 10, or 30 days (i.e. if you chose to search only 1 day and the confirmation was received 3 days ago it will not be imported).
Your confirmations are not in your main email in-box but are filtered into folders automatically. We only scan your main email in-box.
