I'm assuming you're seeing this as an alarm? If you visit this page, does it show a current last authorized date in the column? If it's current then you're likely seeing the same false alarms many others have reported. https://<ise admin node IP>/admin/#administration/administration_system/administration_system_licensing
If your Last Authorization dates are not current for your feature usage, then you could start with renewing the smart licensing config with a new token.
