I changed the order of my photos in VinMotion, but they reverted back to how they were before.

This generally happens when the dealer has logged off of VinMotion and back on. The photos had updated in the cloud server but it takes longer to update across the photo servers at this end. When they log off and back on, the screens refresh from the servers at this end instead of the cloud server. It can take up to an hour for the photo changes to populate throughout the system.
