In the new update (without the map) it’s in the top left hand corner, I’ve clicked in it and got the rewards but then it says immediately that a new chest is ready again
@shell123 and @Crazy Cat Lad This sounds like the facebook glitch that many players have had for a year or so now, where everything repeats like it's the first time you load for the day. If you're at the end of an episode this means you get the chest every time you open the game.
