I've noticed one or more certificates with domain: "TBD" in RCP. What does that mean?
"TBD" means "To be done". That normally happens when you started ordering SSL and did not complete that and saved the request as a draft. This is an order that is not yet sent to CA. You can open it, fill in the required information and sent to CA, or cancel such order.
If you cancel the TBD order, the reserved balance will be returned directly to your balance.
