Software has bugs. If this happens to you (or anyone else), a hard power
reset of your mobile phone will clear up the problem.
I have not figured out what causes the repeating duplicate alerts. I've
asked FEMA and some engineers at a cellular carrier. It seems to be a
"known problem." But I haven't been able to get a technical explanation
for the cause.
The duplication happens randomly on both android and iOS phones, and on
multiple carriers. So I'm a bit mystified about the root cause.

I do agree most people have devices. If there is a reasonable API
method to fetch them then great.
