Wasn't for me. That site's renew button simply starts an order for a new one (as renewal is really just replacing with a new, extended certificate) and sectigo themselves re-did all the company verification, after which my cert was issued. Went smoothly except for waiting ~24 hours for it. If you were trying to get an EV certificate, the process is supposed to be more strenuous on making you prove your operation (sometimes) as well as prove that your certificate infrastructure is secure enough.
