Thanks for the added information, Brian.
Have you heard anything from PayPal regarding this? I am very curious to hear what they have to say regarding this recurring issue. Speaking of, in the past, will the problem just solve itself? If so, it might have to be an issue on their platform where perhaps, an outage/issue occurs causing the gateway to be unavailable for moments in time.
While we wait, I recommend you also reach out to our live support team. I cannot guarantee they will have a solution for us besides redirecting you again to PayPal but it is definitely worth talking to them as they can open up back end settings on your account and see exactly what you are working with.
We will do our best to stay with you and assist as much as we can regarding this but I also want to set expectations that since we are using a third party gateway, there is a chance that we also need their assistance regarding this as it is their own application.
Looking forward to your update.
