Currently, because of the limited space on mobile devices, we feel the best experience for editing a listing is on the web. Please go to http://www.usetrove.com and log in then go to my listings to edit your listings.
If you need to change your availability on a listing, you may do that by visiting your profile screen and then tapping Availability. Updates to your Availability affect each of your listings.
Or, if you are entirely unhappy with the current listing, you can delete it, and then create a new one.
