Hi Jason,
Yes, I've tried the pages on the yellowcircle.co.uk domain and get the same results. I've also tried having the results displayed on a different page than the search form too and I still only get 3 results.
However, depending on the search term used I do get different pages returned so I know my site is indexed correctly in Bing!
If this is an issue with the APi rather than your extension how will things proceed? As WA have a 15 day refund policy I don't want to pay for the extension if it's not going to work properly for me.
