If you happened to click on the link to the unbranded tour and then go look at the branded tour, you will likely only to see the unbranded version upon clicking on the branded tour link.
This is because once the unbranded tour has been viewed, this cookies the browser and doesn't allow you to see the branded tour for a 30-minute window. This is done because many MLS networks have requirements about it not being "easy" to find a branded version of a tour, and a savvy user could simply change the URL to grab the non-IDX link. By inserting a cookie and preventing the viewer from being able to see the branded version for 30 minutes, we've found a happy compromise.
You to fix this issue, you can clear the cache and cookies in their browser and then they'll be able to view the branded version of their tour.
