Occasionally, you may come across an instance where the MLS gives back an error when trying to add the tour link to the listing. Usually, this is due to our tour links being secure (https) and the MLS website not accepting that type of link.
In order to make the tour link work, simply remove the s (so it reflects http), and give that a try.
