Changes made to your listing should reflect on all sites within 1 hour of click the Save button within your account. It may sometimes be as little as ten minutes.
If it's been more than a couple of hours and a change hasn't reflected try making a small change to your listing and resaving. This will trigger your listing to be resent to all websites. This is also a good opportunity to double check that you definitely saved the change.
If you still don't see the change an hour later, please contact our support staff. Our website or one of the third party websites may be experiencing technical difficulties.
