What to do when the certificate expires, and what to do when the order ends. They are not the same thing.

Reissuing is free and unlimited while the order runs. When you need it, how to do it, and what it does not solve.
Renewing means buying a new order: there is no button that extends the one you have. How it differs from reissuing, and why to do it early.
