Ring doorbell won’t record mailman

I was so perplexed when My Ring doorbell didn’t record my mail Cartier every day but got everyone else.I decided to search and found I wasn’t the only one. Reading everyone’s comments had me laughing out loud so I showed my husband who carried mail for 34 years. He told me I had to post his assumption. So first they are not vampires, at least not all of them!!! The mail carriers have a GPS scanner that records their every step back to the post office. The scanner probably knocks out the frequency to the doorbell. Makes sense but thanks for the laughs!!! (Let’s hope the robbers don’t get the their hands on the scanners!)
