Async provider not supported in browsers at the moment

[publicimage]

Hello, I am having an issue trying to mark an invoice as fulfilled.

After marking the invoice as "processed", I get the following error page.

The developer window shows this error.

This happens if I clear my cache, try a different browser, computer, or even the paypal app on iOS.

Anyone else having this issue?
