How come I was booked with a new client without my knowledge?

Got a phone call from a new client re: my watching her 6month puppy the next day. I pulled up Rover and there it was! This was the first time the lady used Rover and was waiting for me to call her back. Is this something new? When did Rover start booking a stay without the sitters knowledge? And yes, I accepted the dog WITHOUT a meet and greet....something I NEVER do except with very young puppies. I'm aware that I could cancel the sit but when I hesitated, she became very concerned..don't blame her either!
