Have you checked the documentation link?
Customers are only required to accept terms and conditions of use on the Meraki dashboard after purchasing an AnyConnect license in order to apply it on the MX. There is no linkage of AnyConnect licenses or Smart Accounts to the Meraki Dashboard or MX Appliance.
I am not a Cisco Meraki employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.
Please, if this post was useful, leave your kudos and mark it as solved.
