I was setting up an AirTag for one of my dogs last night and added a 'Notify When Left Behind' exception for my home address. The Find My app showed my home address ("200 X Street"), and I selected it from the list. After tapping done and returning to the Notify screen, the exception for Notify When Left Behind inexplicably shows my neighbor's address on the corner down the street ("100 Y Street"). This is not particularly helpful since the dog could still be in my yard and out of range of that address. I've already contacted Apple Support, and they recommended resetting the AirTag, but this really seems like more of a "Find My" app issue. Any recommendations would be appreciated!
Verify I'm reading this correctly.
You typed in your address and selected it from a list. However in the Find My app its showing your neighbors house on the map?
IF that is the case. Goto your Contact Card verify the address under Home is your correct mailing address.
Then open the Maps app. You should have "Home" under 'Favorites'
Tap on Home and verify the address there is your mailing address. Above that address you'll see this...
Tap on "Move" (highlighted)....
Then counter intuitively you'll need to move the map (not the pin) so the pin points at your house. Click "Done" and then click "Report this error to Apple". They are pretty quick at fixing the issue in their database (1-2 months is quick for map changes).
What you did there was entered the correct mailing address and moved the Home geofence marker to match the address. So if you said "Hey Siri give me directions Home" it will take you to the pin which is now conveniently located at your house, not your neighbors.
Now go back into Find My and you may need to delete the exception. Make a new one, however this time type in "Home". Increase the geofence to cover the majority of your property.
Give this time between steps because its updating via iCloud and across apps.
Hopefully I understood your problem properly....
