Mine are on .276. Updated. No idea when. Some aren't 'near me', but I'd think they updated as well. The problem, as many have said before, the idea of 'magic updates' is novel, but not at all productive. If it were a 'serious update', does Apple have a way to more effectively push updates? *shrug* Yeah, I'm wondering what a 'serious update' would look like, and maybe it's just not a thing, but it does make me wonder.
IF someone is able to hack them, and the hack spreads quickly (somehow), can Apple push patch the entire universe of AirTags to fix the issue in a short amount of time? In such an incident, patching *all* of them quickly would be pretty important. Just wondering out loud.
