I can't save anything to the Creative Cloud in Photoshop

Photoshop won't let me save anything to the Creative Cloud. This started happening out of nowhere. Everytime I click "Save to cloud documents" the button does absolutely NOTHING, just loads for a split second then shows the save options pop up again no matter how many times I press it. It works just fine when I clicl "Save on your computer" but doesn't let me save to the Creative Cloud at all.
