Why does nothing happen when I hit "submit"?

I don't know what is happening on the back end when you click submit.

I'd suggest calling Rover Customer Support 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].

Clear history and cookies it has helped. This is due to being on Rover a lot, searching. It gunks up the loading after several website visits. I have had this experience with a dog owner trying to book. They cleared everything and it went through. I also know from experience, the site has loaded too many times pops up something like that. So I clear and all good.
