this is the response I received from paypal "
I completely understand your concern that you wish to know about your pending Shopify payment.
Upon reviewing your PayPal account, I can see that this Shopify payment is in unclaimed state. It appears that you might have chosen to hide my email address option When you have logged in your PayPal account using your apple device. So, this has generated a random email address. So, the payment was sent to a random email address. In this case, you can cancel the payment to Shopify and inform the sender the refund can take up to 30 business days. Please make sure to avoid this option to your feature payments. Thank you.
Thanks for reaching out to us! I just ended up mailing my customer the products
