For the default free V1 validation, the system will automatically renew the default certificates after configure a new 13-month identity certificate. For charged validation, please renew your subscription within one month before the expiration of the validation and enjoy a 20% discount. There is no discount after it is expired.
If the charged validation does not renew after expiration, it will be automatically downgraded to free validation. Only the default V1 identity certificate will be configured. You can still continue to use MeSince encryption service for free.
