I've finished clearing up all issues which were preventing my skill from passing certification, but I'm now being told that my "Certificate is not yet valid."
That said, my certificate [i]is[/i] valid, and works in both Chrome & Firefox. It's not a wildcard certificate, was issued by a supported registrar, and should otherwise work perfectly.
The exact certification response is: "The skill is using a certificate which is not yet valid (validity of the certificate is in future) and due to which all interactions with your skill are failing. Please update your certificate to fix the issue."
Has anyone had this same issue pop up recently? If so, were you able to fix it? (And, if so, how?)
