AirTag disconnected suddenly.
My iPhone sent me a notification today that an unfamiliar AirTag was following me, I played a sound to check where the AirTag could be, and it was MY OWN AirTag on my keys. I checked my Find My app and my AirTag is no longer under my devices, I tried connecting a new device but it doesn't show up. There's an option for "found devices" and my AirTag shows up under that, but the only option is to deactivate it, but I am not sure if doing so will make it unusable.
