Releasing Cubes from Tray

I have a simple traybot, and everything works great except for when i try to put up a stack in the goal zones, my intake flaps get stuck on the indents in the cubes. So I can’t stack the cubes that I have in my tray without knocking them over. Does anybody have any ideas on how to fix this issue?

do you have an arm system or are they attached directly to your tray? i outake as i backup and 9.5 times out of 10 it works. only way it wouldnt work is if it was an unstable stack.

Rotate the intake backwards about 20percent
