Are flex drivers required to take proof of delivery photos?

Ignorant customer here -

Firstly, thanks for the work yall do. This job seems genuinely tough, and I’m a long-time Amazon customer, so major props and appreciation.

Secondly, my packages have a tendency to go missing when delivered by a flex driver (now, pls be gentle). Idk what the reasoning is, and I don’t doubt it was probably delivered somewhere… just not anywhere I can find.

Very often, the ~4am - 7am deliveries fulfilled by flex drivers (again, major props. I’m still drooling on myself at that hour) cannot be located. They’re most often marked “signed by recipient” with some misspelled variation of my name (bc I didn’t sign for it), left in mailroom (drivers cannot access our mail room; it’s been an annoyance for everyone involved since I moved in), or left with the receptionist (my building doesn’t have a receptionist). Every time, it’s a gamble on whether or not I’ll locate it somewhere in the lobby, with a ~35% success rate. And no proof of delivery photo is provided 100% of the time. Theft isn’t an issue in our building, but I can’t 100% rule it out. Still, I’m very confused where these packages could’ve ended up.

I had a $200 order delivered today at 6:45 am, which was marked as being left in the mail room. At 8 am, I searched every square inch of the lobby and mailroom - no package. I want my items, but I also don’t want a flex driver to be dinged for a delivery they actually completed.

That said, why don’t flex drivers take delivery photos?? Having some background context clues as to where the package was left would be so very helpful in these situations.

Again, thanks for your work. Don’t wanna get burned at the stake with this post, but after 2+ years, countless missing packages, and zero delivery photos, I’m at a loss - so some insight and advice would be appreciated and mild burning will be tolerated.
