Pogo has released a statement regarding Tile Hero:
We’re aware that some players are experiencing slow load times and black screens in Tile Hero. Our team is actively investigating and working on a fix.
In the meantime, if you allow the game to continue loading, it should eventually start. We appreciate your patience and will share updates as soon as we have more information.
We’ll be sure to keep you posted here when this issue has been resolved.
Thank you I hope they get that fixed soon.
