Send to Youtube broken

I made a score recently that I wanted to send to youtube - unfortunately, it failed. Apparently, my account wasn't verified so youtube couldn't upload a video longer than seventeen minutes. After this, I deleted the failed upload and verified my account. I went back to musescore and pressed the send to youtube button, but all it did was refresh the page. The only message was above the button saying "Your score has been published on the website", but I don't know if that's related. I tried it on different scores, and it did the same thing. I even tried updating the score, then doing it, but nothing happened. Not even on different browsers. What do I do?
