Admob sending Sexual ads in my kids apps. :(

Got this email today from a user on my kids coloring book app. All I have is admob and google is sending adult sexual ads in my kids app.

“Absolutely disgusting! Let my son use this app and an obnoxious sexual advertisement popped up I couldn’t make it stop! It didn’t even work”

Is there a way to disable sex ads from admob?

Have you already customized the filters?

yes, in admob you can go to Monetize -> (choose the app from the list on the left) -> Allow and Block ads -> Sensitive categories
