I've only tested out the cheat code on my computer and my phone, so I'm not too sure how to troubleshoot that. Sorry.
The pinch and konami code are the only two ways to active the cheat in-game, but the cheat toggle is saved as a boolean value under "NO_MILK_RESET" in the options.ini file (same directory as the save file), so if you're willing to do a bit more digging, I guess you could try flipping a 0 to a 1 somewhere.
