Expired code signing certificate
It's been a while since I published anything and I'm running into common problems I've read about in the forums. Specifically, my Apple Code Signing Certification Authority has expired and I'm trying to figure out how to renew it.
Apple's instructions at https://developer.apple.com/library/content/documentation/IDEs/Conceptual/AppDistributionGuide/MaintainingCertificates/MaintainingCertificates.html and https://developer.apple.com/support/code-signing/ haven't seemed to help as I keep double-checking private keys, iOS developer and distribution validity, XCode account preferences, etc.
Is there a way to download that certificate directly? Or some way to generate it? I feel like this question is a broken record but I'm stuck.
