I have a iPhone 17 Pro Max with iOS 27.0.1
I bought 4 new AirTags.
All four are new.
None of them show the setup prompt when I bring them to my phone
All of them show up on other iPhones in my household for setup so I know they work fine. It won't work only on my phone
Bluetooth is enabled and working
Location service is turned on and Find my phone is turned on Find my network also
iCould Keychain is turned on
Rebooted my phone several times. No difference
I did a reset of my network config and my localisation config. No difference
I'm totally unable to find other reason why it won't work
Any ideas ?
