Trouble UPloading to musescore.com

Hi, I know this forum is more about the MuseScore notation software. However, I am having a really hard time uploading a score to musescore.com. It just keeps getting stuck on "score is processing" and the score page will never show up. I tried uploading from both browser and the MuseScore save online feature and I've gone through score properties. Can anyone please help me with this? Also, the piece I'm uploading is definitely in the public domain even though when I search for the piece in the musescore upload dialog thing it comes up as non public domain. Thanks.
