For some reason, my previous Meraki admin purchased a 50 device license for SM. I am not sure why he did this since the first 100 devices are "free". I have used the 50 and now need more licenses. My licensing page only shows 50 available licenses so I assume when he applied the 50 device license it removed the 100 "free" device license. Is there any way that I can get my unused 50 "free" back? Or can I remove the 50 paid license to get 100 free back?
