Farm Merge Valley

I completed the sticker book and have still not received the crates or energy yet either. I didn't receive the 90 crates I claimed in the new challenge. I lost crates and energy bonus for completing one of the categories. They pop up then freeze and are gone. I lost two hours progress the other night. Game freezes and progress is gone. Frustrating.  I have a brand new tablet and just use it for games. There are a lot of bugs in this game.
