@Taf_2049 Generally this issue may be due to not app update or device software update. Tell me what device you using for this game? I will ask to check some troubleshooting.
@Taf_2049 It sounds like you're referring to the feature where players could choose between 2 quests (send 10 lives to friends, beat a level with hard or super hard difficulty, collect 200 green candies, use a fish booster and hand booster in a level (imo the dumbest of the bunch; who's gonna waste a hand switch for a hammer?!)). From what I've heard in this forum, King is often testing on different groups of players with features they may or may not introduce. The daily quest also disappeared for me around the same time as you. I doubt it'll return since it was an easy way of getting boosters, and King doesn't want that. Cuz, y'know, $$$$
I also lost my daily Candy Quest around a month ago. Fully agree with Deryck; it was a too easy way for the players to get a nice number of boosters, so not interesting for King to continue. I assume they have removed it from everyone, not just from a test group.
