I can CONFIRM it DOES NOT. The page first jumps with the multiplied exp but upon recheck in the menus they only leveled the normal amount. I'll repeat and I also speak other languages; it does NOT work in normal battles. If you keep spreading this false info the code will never get fixed, please stop this nonsense. Not only does it screw up some of the UI while keeping EXP non-multiplied, it screws with move learning. My mons since I've used that code every level want to learn the last level-up move in case I dis it. We need a better approach at a EXP multiplier and a lot better cheat code. More so, when it does work (only in the let's go scenario) that's useless because guess what, a lot of moves pass you by, most mons don't evolve if they're not in the overworld, mons don't gain EVs with Let's go battles. Even if you argue it works for that small part of the game, that's the most useless form of battle you can do. It needs to be proper and work with normal battles.
