Hello, I've recently created a merchant ID and added two domains to it. I placed the verification .txt files in the right place (under the .well-known dir) and both verified successfully and show as such in the merchant id setup page. I am intermittently getting the following error: { "statusMessage": "Payment Services Exception merchantId=XXXXX not registered for domain=my.domain.com", "statusCode": "400" } (merchantId and domain have been masked in the above error) -- What's odd is that this is intermittent -- It'll work fine, and then stop and start giving the above error, and then start working fine again, with no intervention from me. Some context: This is a single server application, so it's not like we've got a server out of sync somewhere. Thoughts? Any thoughts?
