Nexus 6: Can't preview files nor open them via Drive app

Is it just me? Or anyone else having issues Sith Drive app on their N6?

N10 & N5 worm just fine.

Tried removing it, rebooting, reinstalling - Log out & logging back in - Clearing cache (and data)

There a no precies thumbnais. The documents are there, nut won't open, like they aren't really there.
