Jazz is

The game is bugged and automatically stops/closes within 10 seconds every time I try to open it on my device.

This is a problem they are supposedly aware of. But they aren't doing anything about it and their support services go out of their way to be useless and disrespectful to the players, I'm assuming because it has met resounding success with the vast majority of players that this is not true for.

They should not have released this game until it was genuinely playable and I'm so disappointed by this.
