Why no ads showing

Hey there, are you logged in? If you have logged out, make sure to login again to see if that solves the problem.

If you uninstall the game then unfortunately the game will lose it's boosters. As for the ads, this along with other events can come and go in the game as the game studio tests different versions of the game for players.

Hope this helps! Let us know if you continue to have problems with the game.
