You can see my test project here, to use it you will have to replace the publisher ID and App ID with your own.
Also it is important that you change your ad technology provider list from default to custom and select a maximum of 12 providers, otherwise it will fail to load the user consent dialog.
I'm intending to take a look into the iOS version again soon, along with location testing. If you find any replicable bugs please file a bug report on the GitHub tracker, you will get a response from me faster. Also it's hard work trying to understand bugs from forum posts.
I have downloaded and tested the project and it kinda works, I have some questions though:
About the privacy url - Do I need my own url? How do I make one? What should be in it?
In the parameters dialog for creating an ad in the field "Advert unit ID" you have put "TEST", can this be anything just to name the ad or should it be the ad unit id from admob?
All other buttons work even though I have only made an ad unit for interstitial, why do they work anyway?
Hope you have the time to answer these questions :)
