ads for bonuses stopped showing. Is it normal?

I always had a random reward at the start for overpowering ads. I could have skipped it or played it additionally while watching it. or when you run out of moves, watch ads so as not to lose gold like 5 moves just to get through? Will they come back?

Whether or not your adverts come back is dependent on if you purchased anything with real money @Zielak. If you have used your own money to buy a booster package for your game then your adverts will not come back to your game.

If you haven't purchased anything though your adverts might come back. I lost my advert features for seven months last year.
