I just replaced one of my laptops, and I signed in and tried to add it to my managed devices so I can access it remotely, but when I click "Add device", it says "Active", but this laptop does not actually appear in my list and I can't connect to it from my other laptop. The laptop I sent away for repairs still shows in the list, and I can't delete it, and I'm wondering if it somehow things the two are the same?
How do I fix this so that my old laptop is gone, and my new one is accessible?
