Licenses will be auto renewed. check out this link
...if you fullfill the requirements:
**CMNA Refresh License Requirements:
**Your Dashboard Organization needs to be compliant, so all devices need to be licensed. The licensing also needs to be active and not expired. Compliant Organizations are those which have a CMNA promo license key applied, have 12 or fewer applied licenses and have active/current licensing. The program will not renew non-compliant Orgs, or those that are partially licensed or expired.
To contact firstname.lastname@example.org. is certainly the right thing to do...maybe needs some time till they answer.
If all this does not help...I would contact my sales rep of Meraki.
hope it helps
