It's time for me to update my Apple Pay merchant identity and payment processing certificates. The first step is to go to the Certificates, Identifiers and Profiles page and edit the appropriate certificate, but none of them have an edit link, either on the listing or when I click through, despite being signed in with the account that created and owns the certificates. I can download, I can revoke, but I cannot edit. All the guidance online, published by Apple and anywhere else, as far as I can tell, talks about editing your certificate entries on the Certificates, Identifiers and Profiles page. Has anyone else seen this and is there a solution? Creating new identities is a much more involved process than simply renewing a certificate, so I'm keen to avoid going down that route. Many thanks.
