While we want our players to progress at a healthy pace, the video ad network partners have asked us to put daily limits so that ad consumption can be balanced over time.
For folks watching video ads until ads can't be shown any more, this basically means that we've exhausted the supply of video advertisers. Please know that we do want more ad networks to provide us with that supply, but we also try our best to work with partners who have integrity and show ads that align well with our game.
