Hey Manager,

Thanks for reporting the issue!

Are the adverts in video form (for free boosters) or are you talking about the offers for free tokens? If it's the latter then can you specify the offer provider of said ads?

Also:
-If you're on an Android device, please clear the Top 11 app's cache.
-Try reinstalling the app after that.

And if you have the option, can you check if this issue occurs when you run the game on another device as well?
