Google Play - inappropriate ads violation email

I got another inappropriate ads violation email, which I thought I fixed via the max_ad_content_rating settings:

     AdRequest request = new AdRequest.Builder()
                                     .AddExtra("max_ad_content_rating", "G")

But unfortunately I got an email saying App Rejected. The status on the app on the Play Console UI says Update Rejected, but my app is still up and when I click on my game via the UI, it says “Published”, but there is an alert saying I need to make changes. I’m confused.

Is the Google Play Console simply buggy, or did I violate something? Should I fix my app or is it already fine? I’m scared of getting a strike if I don’t do something.

Now it says it’s published. The rejection message is gone. Guess it was a delay.
