Adsense mobile placement

I did not work with Adsense in a long while, I am wondering if this type of placement would be against their policies.



It's a sticky ad which stay as the mobile user scrolls down the page.

I remember I've seen it on many apps and also on sites. Haven't found something clear on other forums, some people use them, some don't. I want to please ask you to share your thoughts.

No you're not allowed to use adsense ads in a sticky form that follows down the page. You can check their policies online.
