Once you click on the Mystic Vision Tower, you will be briefly taken outside of the game and shown an ad. This process is handled by a third-party agency and we cannot guarantee that it will function correctly for all players at all times. Ad availability depends on location, so sometimes you may not have any ads to watch. There may also be ongoing technical issues preventing certain players from watching ads.
We unfortunately cannot provide support for such external issues, but please note that many of them are temporary. If you’ve just encountered one, please try again a bit later.
