A complete disaster in daily quests since the January update. I understand that advertising is the engine of progress, but not so much that it completely slows down the game (and time passes). Each game has two windows with advertising. I don't mind letting it hang, BUT IT DOESN'T UPDATE during the game. You poke one cell a hundred times to make it open, and the animated face makes a thoughtful pose, saying, “I’m thinking.” It became inconvenient to play. The only plus in the latest update is that ALL games for the day are shown.
