We're having an issue where once we get the response from our backend with the session information and passing it into completeMerchantValidation. Basically the "Processing" spinner stays for about 10-15 seconds then just fails saying "Apple Pay Not Completed. This website was not able to complete the payment. Please try again."There are no console errors. It's a valid response from Apple. But no details as why this is happening?I've ensured that the response we get from Apple is the exact object that's passed into the completeMerchantValidation call. I even put a console log after this to ensure no exceptions were thrown.iOS 11.1 (15B93)This was tested over wifi and cellular network.I have now tested this on 4 different devices and it happens on all of them.

I've got an issue and I can't get a hold of Apple through an official TSI. I am hoping someone can help me out here. We have a massive application where our customers have their own unique subdomain. We'd like to offer Apple Pay, but I can see handling certs for every subdomain, in 3 different environments, being a maintenance nightmare.Does anyone know if Apple can do wildcard certs or if you can just have one cert for one domain and it handle ALL subdomains?
