It's a new thing with Amazon since the pandemic I think, contactless delivery, they will leave it at your desk, ring the bell and text when it's there. Think they have a notification part on the app if you know you won't be in to let them know.. its still very much not ideal though for the multiple reasons outlined. Systems out of sync etc. I'd definitely bring it up with Amazon anyways as any dealings with them that I've had they have always tried to amend.
