we have an uploaded custom SSL certificate for our site and it will expire very soon.
Right now it is not possible to renew it (extended validation take some time),
but we have an universal SSL certificate which is pre-installed in Cloudflare and which could cover our needs while we request a new EV ceritifcate.
Do we need to perform any actions to enable universal certificate?
Do we need to delete expired certificate before it is expired?
Will universal certificate be used automatically instead of expired one?
