Frustrating design flaw

When I play Farm Merge Valley, I will open several crates at a time, sometimes half in one go. If the game suddenly switches to the challenge screen, as it does occasionally, in the middle of opening crates... I will inadvertently activate a challenge for a different game when the screen switches. The crate button from the game and activate button from the challenge screen are in the same spot on the screen.

Also.. While I love the idea of daily goals in any game, the ones in Farm Merge Valley are grossly unachievable unless you either play nonstop all day or pay an obscene amount of money to get extra crates, energy and crystals. Do better.
