Air tags not connecting
Thought I’d connected them to my iphone 12pro early this year, but they don’t show up in Find My… not sure if they ever did.
I also don’t see a way to add another device there.
iPhone 12 Pro, iOS 17
Question marked as
The Apple AirTags would show up on the Items tab, not the Devices one in the Find My app, as Apple deemed them as "items."
If they are not showing up there, I suggest that you reset them, and see if they do afterwards.
