My game implements Unity ads, and is designed with a universal audience in mind. As such, I would prefer not to have 18+ ads (or even 13+ ads depending on the circumstances) appearing in it, especially since it would appeal to younger audiences as well. My question is then, how do I prevent age-inappropriate ads from appearing? Is there a way to simply set the age limit or content restrictions on Unity ads? The only setting along those lines that I can find is the COPPA toggle, and that would cause other issues (not to mention that it wouldn't do anything to the ads). I've looked in the dashboard for a while, and I've tried to research it beforehand, but the fact that they've shifted to a centralized services page, redirected all the old links (breaking them in the process), reorganized the settings in the dashboard, and 404d their FAQ post on the topic doesn't help either. Blocking ads based on a rating would work too, as I would have to get one because I am publishing to Google Play.
Edit: The second link only 404s some of the time. I just happened to get it every time before asking this question. Bad luck, I guess.
