privacy settings broke?

Earlier today, I switched my privacy settings to "off" and added a security pin. I don't know if that's what caused my Roblox experience access to be restricted or if I accidentally switched that on, but that was there too. Anyway, when I was done playing with the settings, I decided to switch them back to custom. Everyone could message me, friends could chat with me in the app, and everyone could chat with me in-game. These were the settings I had always used. Yet they didn't update. It says they're updated otherwise, but that isn't the case. I also changed my account age back to 13+, as it had otherwise assumed I could only access content appropriate for all ages, but that didn't seem to do much either. But my god, it's frustrating. I can't chat; I can't even tell my friends that my chat is disabled. I can message, which is just...why the fuck is that useless feature the only one working? I tested this on an alt account to see if it was just a "me" issue, and, nope, it's all Roblox. I tried contacting support but got "too many attempts right now. Try later." And yes, I made this account in hopes of fixing the issue I'm having with Roblox.
