Experimental Mode is the same as FilteringEnabled if I am not mistaken. I went to the Develop page to upload a new game icon for my game, but I noticed that it said the game was Experimental:
Naturally, I get a bit confused - I’m certain I have FilteringEnabled active in this game, even though it’s so early in development. I was correct - FilteringEnabled is true. I have tried publishing the game again, but the Develop page won’t remove that “Experimental Mode” flag from it.
