Why are my projects no longer updating on certification link after editing and saving them?

I didn’t know that by claiming the certificate, I would no longer be able to update the cert link. I was planning on going back and editing more stuff.

Which “cert link” are you talking about? You should be able to resubmit projects.

The link that i post on my linked in, that can show you the projects and their code.
That link still has the non-updated code
