IIRC, this indicates that it's linked to someone else's account, and has not been shared with you. The "beep when moved" feature is to alert people they're being tracked.

For example, I let my mother in law use luggage of mine with an airtag still in it and every time she moved it after the first day or so, it would play a noise.

I had the thought too, but there is no way anyone else could have gotten physical control over this and shouldn't I see that AirTag when I scan for things in my surrounding as an anti-tracking protection?

I've had similar issues -- consider it a bug -- and unpair and re-pair with your phone, and likely the issue will go away.

		I think I unpaired it, but I cannot pair it again, as it isn't recognized by the iPhone at all.
