My Sesame was not performing well, so I decided to remove the existing lock and re-add it. Also, my wifi access point was no longer visible. It flashed blue, but never showed in the app. When I re-added the same lock, all went well until I tried adding the access point. It was seen and identified, but when I tried adding it, it said "Bad request. This wifi module has been registered by a different account. Please ask the previous owner to unregister...". I had done the straight-pin reset already. It now is a steady red light. I am the previous owner. The access point module had never shown up in my app to allow me to "delete" it. How do I accomplish what the notice is telling me to do? Since I am the previous owner, how do I now "unregister" the module when it was never showing up in the first place?
