iCloud stopped syncing

Hi,

iCloud stopped working for me. Atleast for Pages it doesn't sync. If I edit a document on my iPhone or iPad it would sync to iCloud but not sync to eachother. This is very annoying since I used to type up some stuff on my iPhone during transit and then continue to edit on my Mac, but now I can't seem to do that.

My devices do sync to iCloud.com, just not to eachother.
