Hey @YouTube I don't have kids nor do I really like them all that much. I'm also paying to avoid ads. Now tell me how to permanently disable that stupid popup for the youtube kids app.
Oh, sorry for the confusion. Can you check if your YouTube app is up-to-date? If it is, try clearing cache & data or reinstalling the app. If none of those work, send feedback with the steps here so we can pass it along: https://yt.be/help/feedback
