My Find My showed “No Location” for my AirPods as they were dead. But now it’s completely removed them from the find my app.. is that normal? Or have the been stolen and reset? I was sure they were in my car or home somewhere, but now I’m concerned.

It's normal.

Last known location only shows for a limited time, something like 24 hours.

I had this problem too except two weeks later they showed back up with a “no location found” status. They stayed on the find my device page for about 24 hours then disappeared again. Now another week or so later they have reappeared, again with a “no location found “ status along with someone else’s AirPods. What is going on ?
