When I try to move the PIN on my desktop to the correct location, it says "saved" and when I log back in, the pin has reverted back to the original incorrect spot.
When I try to move the pin on my mobile app, it says that I don't have permission to do so.
If you are unable to move your map pin yourself, you will need to contact Airbnb to get them to do it for you. This Community Help Guide explains the best ways to contact them.
