Airtag accuracy on more than one Find My devices
I have Airtags on various devices like vehicles and even my dog but the thing I find frustrating is not how accurate they are or battery life but if I look at the Find My application on different devices, MBP, iPhone or my desktop Macs, I get different locations for the same Airtag. Sometimes it takes days for them to all sync up and be the same. I sometimes can look for the location of my dog which is always with me and it shows his location somewhere I was a few days ago, maybe in another state, but the other Airtags I have either on me or in a vehicle I am near are correct. I doubt there is anything i can personally do to change this. I keep all the batteries fresh.
