Why can't I see a message I've sent through Rover to a potential client?

It sounds as though you are writing this message to Rover staff. While some Rover staff do participate on this board, it is isn't the official way of communicating with them, This board is primarily for sitters and owners to discuss pet-related or sitting issues.

You can click on the Help link on the top of the page and you'll find a "contact" Rover link or you can call them directly at [Edit: Rover’s contact options have changed. Visit the Rover Help Center at https://support.rover.com/ to find the phone number, help articles, or chat with the team].
