I set up 3 new Airtags on my iPhone 12 Pro. Working perfectly, precision finding working and guides me to each airtag as it's supposed to, and can also trigger them to play a sound. Also set up 3 different Airtags on my wife's iPhone 12 Pro and they're working perfectly too. Both phones are running iOS 14.5.1
The next day I'm demonstrating them to my sister and precision finding won't work. It just says 'Connected. signal is weak. Try moving to a different location' and displays the pattern of moving dots as if it's trying to locate the Airtag. It does this will all 3 of my Airtags even if I'm holding the phone right next to them. I've restarted the phone, deleted the Airtags from the phone and re-added them and taken the battery out of the Airtags and reinstalled but still the same message. I can play a sound on the Airtags though. My wife's are still working perfectly with precision finding.
I'm thinking it's a problem with my phone as it's the same with all 3 Airtags. Unlikely to be a hardware issue as it was working when I first got them. Don't really want the hassle of resetting the phone or the network settings.
As a further test, I removed one of the Airtags from my phone and added it to my wife's. Precision finding with her phone worked fine with it. Removed it from hers and added it back to mine and precision finding still says the signal is weak and precision finding won't work.
Checked in settings. Privacy - Location Services - Find My 'Precise Location' is enabled.
Tried it with wifi turned off and with mobile data turned off too.
Turned the phone off for half an hour. Same problem when I turned it back on.
