Airtag issue with new iPhone
I had a previous iPhone and it detected the Airtag inside my car, even from over 1 km away. I just got a new iPhone 12 and restored the backup from my previous iPhone. The problem is my new iPhone 12 has difficulty detecting the Airtag (paired with the previous iPhone) when I put it inside my car or even in a cabinet 3 feet away. Only when the Airtag is next to the iPhone 12 is it detected. What is causing this issue?
