I open the Windows Explorer (A Window, where all my folders are).
Normaly there are folders and Files, with a little Icon, where I can see wich file it is (Foldericon for folder, Blue PS Icon for PSD File and so on). If the Cloud Sync, the window open, but there are no Folders and Icons. Only the green Loading Bar groth total slow.
And the Little Icons are often only a white icon.
Than I kill the Task "Core Sync" and everything works fine.
p.s. sorry for my english. Hope you understand my problematic
