Roblox "Enter" key not working when I try to send chat on any Roblox game!?

Please help! I know this is for script help but I didn't know what else to do, yesterday I was on Roblox and everything was fine but then my chat enter key stopped working! It lets me type but when I hit enter it doesn't send the chat it does nothing! Please please please help me! I am on chromebook and I have tried restarting my settings, shutting down my computer, trying to change the keyboard/ other stuff. My friend had the exact same problem and I am not sure she fixed it either, could you please help me?
