iCloud.com notes on Windows won't save my changes

Hi, for the past week my notes on iCloud.com (on my Windows desktop) won't save or sync my notes. It's working fine on my iPhone. But only one note on my desktop actually loads (my to-do list), but any changes I make just won't save. I can't even access any of my other notes. I use this every day to keep track of lists, and it's frustrating to keep losing info.

This the only one that works, but it just keeps saying 'saving' and doesn't ever save

And all the other ones just say 'loading':
