Having similar issues. Received a notification that the SSL certificate is expiring. Under the Certificates, identifiers and profiles page, it seems that the only cert that is expiring on the provided date is our Merchant domain cert/txt file. Clicking the verify button, downloading and uploading the new .txt file and clicking the second verify button all seems to be working but there really isn't any successful response or message. Clicking verify redirects back to The Certificates, identifiers and profiles page and the expiration date fails to update. I am pretty sure the verification is working because there were a few times were we were not redirected to the Certificates, identifiers and profiles page and instead were met with the "domain verification failed" pop up; this was due to apple seeing our cached .txt file. However, once we fixed that, we were re-directed back to the main page but again, the expiration date has failed to update. Am I missing something? It mentions updating the SSL but is the .txt file the SSL? Or is there some other cert that needs to be updated that isn't displayed on the Certificates, identifiers and profiles page? All I have access to through apple is the Payment processing certificate, Merchant identity Certificate and the merchant domains (.txt files). I can't believe there has been no resolution to this issue. I have seen similar threads dating back several years.

Did you ever figure this out or did it resolve itself? I received the 30-day notice email and promptly updated the domain. I clicked the verify button, which took me to the download/verify page. I downloaded the new file, uploaded it and everything was working fine. Clicked the verify button and it goes back to the Configuration, identifiers and profiles page. The verify button is still available (rather than greyed out) and the expiration date does not update. I have done this multiple times with the same results. Figured that per Apple's documentation stating that they check every 30, 15 and 7 days out, that I could wait until 15 days and the date would change. 15 days passed yesterday and still the same. Downloaded and uploaded a new .txt file and re-verified even after removing the domain completely. Verified fine but the expiration date is the exact same as before...prior to remove the domain... Any thoughts? Again, I am just going to leave it and pray that on the 7th day, the expiration date just updates itself...otherwise I am not sure what to do. All of the other certificates have expiration dates way later this year. The only thing that is expiring any time soon is one of our three merchant domain verification txt files. Do I perhaps have to just make a totally brand new merchant identity certificate and renew everything?
