iCloud Drive doesn't sync on my MacBook Pro.

Hello there.

I've noticed many issues with iCloud Drive since they activated it on Yosemite. I only can manipulate it via Safari (add or delete my files, move it into folders etc), but it doesn't sync in Finder on Yosemite. When I've tried to refresh Drive in preferences or log out and re-login in on the entire iCloud, it didn't helped at all. I feel really sad when I cannot use something that would help me a lot. There are only a few files downloaded - Pages, Scanbot and Preview. There are many others still waiting for download - files, videos, zip files - any types of file. Is there any possibility to force the sync manually?

Thank you all for your help.
