MLS has their own support desk for any questions or advice that you may need regarding the uploading of photos or tours to their system. Of course we don't know how their website works and that's why we have to direct you to them. However, we do know that it's a simple process. If you want MLS support to advise you on how to upload a tour link to your MLS account, please be sure to tell them that you need to know how to upload a tour link and not an embed code. If you refrain from using the word video with them and say tour or virtual tour, you should get the correct instructions from them. If you mention video, most of the time, they will incorrectly advise you on how to upload our tour to their system.
