Unity Ads & Parental Gates -- Apple App Store, Kids Section

I tried to implement UnityAds in my game for an app in the Kids section of the App Store. The app was rejected because:

"Guideline 1.3 - Safety - Kids Category
You have selected the Kids category for your app, but it includes links out of the app or engages in commerce without first obtaining parental permission. Specifically, your app includes advertisements that, when tapped, take the user to a web page or the App Store.

Next Steps
To resolve this issue, please update your app to add a parental gate before the user can leave the app and ensure that the parental gate cannot be disabled."

Is it possible to do so with UnityAds API? I really don't want to give up on the monetization opportunity. It really would surprise me that:
- there's no way to add a parental gate after an interstitial ad is shown;
- there's no way to declare ads not to take users outside of the app. There should be an option for that;
- there's no workaround in general.

Has anyone else found a workaround for this? Placing the parental gate before showing an ad doesn't make much sense to me. Really want to avoid that.

 

There are other ad networks that specialise specifically to being kid safe. Maybe you need to implement one of those instead. You may also find you get more ECPMs seeing as the specialised kids safe network will only be serving kid safe ads aimed at kids and parents.
