Will you help me troubleshoot a product that is returning “things don’t seem to be working right now” from PayPal? Payment for my other products

That's an error on the Paypal's end. It's either the email isn't configured to accept payments or it could be due to incorrect Paypal settings. This solution might help https://docs.easydigitaldownloads.com/article/2030-paypal-error-things-dont-appear-to-be-working-at-the-moment

Let us know how it goes. Thanks

Looks like it’s back on track, thanks.
