Why didn't paypal receive my money?

I would start with Rover support @ [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] , they can check the transaction for you

I just connected my Paypal account and sent the money over but its telling me expected release date is a couple days from now? How is that fair?

How long did you wait? My first transfer to PayPal took almost a week.
