Hi @lbellingham, I don't think it's a glitch as much as it's a very difficult
level. You can read a tip from this link. She is very good at writing
tips so you might want to hold on to her link for future levels.
I noticed that several people had issues with this level, so I tried to clear it today. As I played this level, I try to obtain the yellow candies before removing the wall’s top level - below the pass through. Doing this, the yellow candies or check marks cannot move down the right side. I mistakenly removed the top portion of the wall, so I kept playing and then the check mark or yellow candy appeared mysteriously above the remaining wall. The issue doing it the way I described is that you have to hurriedly clear the remainder wall.
