GUI appears only on private server

Hi. My game Meme Maker (Meme Maker - Roblox) has become popular quickly (20,000 sessions yesterday and rising). I am very happy with this and think I’m on to something, But I am having a weird GUI problem. If you go to the game (feel free to try) and create a private server, you will see a purple FEEDBACK GUI button on the top left. But if you join a server with others it is not visible. I have tried for over 24 hours to publish to the game, I’ve shut down servers to publish, and nothing changes. I also changed the game to private for 5 minutes to give time for the code to publish : what’s even stranger is when I joined a regular server with others I DID see the feedback button but then after a few minutes (or possibly the next session, I can’t recall) the button disappeared. So my question is: WHY does it appear on private servers but not other servers? I really would like to fix this so I can collect feedback from players. Thank you. Kevin

Can you please give the script and pictures of the Gui, and what type of gui it is?
