Hello Chefdivinfo,
As you had renewed the licenses, i assume you would have a PAK key ready.
If so, when you reach out to Cisco, please request for the licensing team to assist you to activate the PAK and they will be able to send you your license keys as well in an email to manually apply to the ESA, or wait for an hour or so and click Check for New Keys and it should auto retrieve.
If the PAK has not been registered and activated, your device will not be able to retrieve the keys automatically.
Regards,
Matthew
