Hi, my previous company was throwing one of these units away (worked perfect) so i snatched it up and hung onto to it for a while. I just looked recently and saw them listed for like $80 on eBay, so I listed and sold mine. The buyer just contacted me and said "The serial number for the unit you sold me remains a part of another system registered with Meraki. I can't use this until you provide me the release code so that I can release it from your system. Please provide refund or release code".   Does anyone know what they are talking about? I guess I could just send them a refund, but thought I would check here. I dont have a way of getting them a release code at this point, if that is a real thing. But I thought I would post this to see if someone know of another way, and to know if what they are saying is true. I'm happy to refund them if its legit. But I'd also like to help them if they're confused. Searched online for a while but couldnt find anything.   Thank you for any help you can provide! ... View more
