Please add t.paypal.com to whitelist

I was attempting to pay for an online food order from a restaurant using menufy.com. I was able to login to PayPal during the checkout process. However, when I clicked on the "Order Now" button, I received an error message stating payment processor is unavailable. I immediately checked Pihole. It had blocked t.paypay.com, among many other domains during the checkout process. I manually whitelisted t.paypal.com and attempted the payment again with success.

Thanks!!!
