I’ve also found you can go through your history and add videos marked as Kids that way.

Totally anecdotal, but I’ve reported a couple of non-existant roads to Google. I occasionally check because I’m curious if they ever updated them, but Google still tells me to drive through a walking path and walk through a fenced off private property. It’s been years at this point. I don’t have an iPhone so I don’t have any experience with Apple maps, but maybe they’re better at taking user reports into account?
