Advanced questions all of a sudden don't work

So, after actually pulling through and giving ChatGPT Plus a try, I just logged in to find out I can't even do an advanced question (the kind I pay extra for) because "I can't use the model right now". Yeah, okay, so what else can I do here then? It's just like you have to build up your entire day around ChatGPT because you start trying to do something and you just have to stop and hope that maybe it works in an hour or two or tomorrow. It's absolutely brutal.
