Amazon Deliveries missing off my Ring camera

It’s a the holiday season, and Amazon stops at our house most days. For two days in a row, our delivery did not get picked up by our camera. We’ve had this happen before but we’re tracking it now.

Do they ways to befuddle Ring cameras? When we go out to pick up the package, it picks us up, just not the drop off. Might explain drop offs where Amazon says we got a package, and they sent us a picture, but there was no package to be got a few minutes later; porch pirates working as a team?
