Why in the world did you set the ad free like it is?
When I saw just a couple of dollars for a one time buy-in to remove ads, that was a no brainer. The way the game functions afterwards though needs to be reworked and updated. Not only does the game give you a level finished reward (say 100 credits) but it will pop up the option every time to watch an ad for double the credits. HOWEVER!!! If you paid to have mandatory ads removed, the game is rended incapable of loading ANY ads (requested or not) and thus makes it so that you cannot get that double the credit option whatsoever. It also affects the capability to check off any square of the free daily items. Something needs to be done to address this.
