Airtag won't reset
I have 3 air tags, which were delivered to me in July 2021.
For some reason they all dropped their connection to my iPhone 11 Pro Max. I removed these airtags from Find Me with the intension of resetting them and then re-adding them via Find Me.
I have followed the AirTag reset instructions, however no matter how many times I take the battery out and put it back in again (i've tried dozens of times), the 5th chime that indicates a reset does not play, it's just the same chime every time.
This happens on all 3 Airtags.
I am now no longer able to add my AirTags to my iPhone. I have also tried this on another 2 iPhones I have and this didn't work either.
iPhone 11 Pro Max, iOS 14
