Like the game but stuck on level 518 – Toy Collapse: Pop Toon Bubbles Review

I like this game but am stuck on level 518. I drop all 4 targets to the bucket but they do not go off screen. I closed the app. Still reached the same endpoint. I have reached the same stalemate on this level multiple times. Eventually I just use all my moves. Help please! I tried a direct email to the developer and it bounced back as undeliverable.
