Hello @Tatania1
Here are the steps to change your cover photo:
==>Go to listings
==>Click on that sole picture you see under Your listing
==>Your screen is split in two: Listing Editor and Photo Tour
==>Top right hand corner you see All photos. All of your photos show up and select the one you would like to have as your thumbnail photo
==>On the right hand side you'll see a caption that says Make cover photo
With this new format, only the first five pictures can be dragged and dropped to be put in the order you want your guests to view your top 5 pictures. Impossible to do once they have been put by room and we can't change the order of the rooms either so every listing will start the photo tour with the living room.
I hope this helps and give me a shout if need be😊
