It's the classic problem: you have a system that's useful in the 1% case but not in the 99% case. Over time, normalization of deviance causes you to extract functionality from the system so that it responds to the 99% case 100% of the time. When that 1% occurs, your thing breaks.

Obviously the call center did this. Pretty typical.

In any case, I have an Airtag in my car. It's pretty good. Maybe I should just wire in an old iphone on a data SIM.
