@eli it’s completely silly that it doesn’t work with Family Sharing. We bought a 4-pack and have one in each of our vehicles and there’s no way to not have one of us constantly getting the “AirTag Following You” notifications
And now dead again, along with some old unused API keys, which proves that this was intentional and we and others were specifically targeted.
I wouldn't have swapped out the keys in the first place if there was even a shred of communication. Figured if nothing else this would push the issue.
Oh well, on to smaller but greener pastures.
