We design the game for all types of players. Some play to compete, others to relax.
Therefore, you don’t have to participate in Competitions if you don’t want to — you can just opt-out.
To do that, please go to your Settings > “Advanced” tab and make sure the “Don’t participate in Competitions” option is checked.
When you check this option and Competitions are going on, you will be allowed to sell from your barn.
Also, checking the option will reset your Competition stats (orders, XP, and coins) for the current edition of Competitions.
IMPORTANT NOTE: If you do the Bellflower Meadow update, selling from barn will be permanently disabled. Even if you check the “Don’t participate in Competitions option”, selling from barn will still not work.
