FOID delivery issues

Hello. Has anyone in cook county been having issues with their FOID card delivery? Twice in a row USPS has refused to deliver my FOID card replacement. Every time my mail delivers fine until I place the replacement order. Once I do, they mark me in their system as “No longer at address” and then send all my mail back as “Return to Sender.”

Possibly a coincidence but it’s happened twice when I was expecting a FOID.
