Hi and Happy New Year!
I’ve made an AdMob extension. It is well documented, has a demo project and it targets the latest AdMob API.
Please check it out.

Github page: https://github.com/Lerg/extension-admob/
It supports banners, interstitials and rewarded videos.
It’s easy to setup and use.
So feel free to try it and ask any questions.
Thanks!
