Meraki reseller didn't do our licensing properly. After 30 days, Meraki shut us down (2 units) and sent an email... No Internet for half a day. They can't send a warning a few days ahead of time? Not very customer friendly.
I'm with Blake here. You receive a warning well before the org expires. And even then a grace period is started. During that period you will receive lots of emails warning you. Only after all that you get disabled.
Are you on co-termination or per device licensing?
