Adobe CC Library not syncing, no error, just not uploading

Hi, CC Libraries have been inconsistent in connecting and syncing. Sometimes files sync no problem but now no files I am trying to upload are syncing and colleagues cannot access my files in the library. I am uploading my files to my CCLibrary, I see them locally, but they are not synced to the cloud (I cannot see them when I view through a browser). When I pause syncing, the syncing Icon spins for a secoind then stops. We are trying to embrace libraries across our organisation but this is becoming frustrating.
