As soon as I upgraded to paid version, Chatgpt stopped working

I finally decided to upgrade to the paid version and I could no longer continue the chat/thread I’d been working on for hours. I started getting an error to contact support.
I went to continue today, my chats are gone, and there’s no place to even log in, to add to that, I can’t get an output to any query. Nothing.

Worked find before paying- yes I have signed out, and back in, deleted cache, everything.

This exact same thing happened to me this morning. Working fine then as soon as I upgrade and pay, nothing works. What gives?
