This is probably relatable to people who have parental lock on roblox

Try reinstalling Roblox or make a new account.

Well uh
I can't do that if I can't open the website

So you meant parental lock on your OS and not on Roblox itself I guess.

Sometimes when a game is too laggy my screen goes black but it doesnt turn off. (Mobile btw) if this happens to you just press tabs and go back in, and boom it's better and you didnt leave the server. wont help the lag though
