Arlo Pro 3 is not detecting USPS

[softwire]

I have two Arlo Pro 3 cameras.  My network connection is great on both of them.  Both cameras record and notify me of any movement.  I haven't had any issues with them and they catch any movement that a human or animal would be making.   The camera picks up all packages delivered except when USPS delivers.  Amazon, Fedex, UPS all trigger the camera.  However the USPS do not trigger the camera.  Just today they delivered a package and picked up a few packages and the camera didn't catch it.  This has happened a few times in the last month and it only happens with USPS.  The cameras are on and don't show any issues.  Network has been fine all day and has recorded our dogs going outside and my wife getting home from work.  Thoughts?

Based on your description, it sounds like the USPS delivery person somehow isn't triggering the camera at all.  Is that the case?  Or is there a mis-tagged video in the library that shows the delivery and pick up?
