I suggest then, that you take it back to the store and swap it for another, and check OneDrive before you leave. I bought a 930 at the weekend, and OneDrive works just fine for me, so it's not a problem with the OS.
With such a new unit, it's probably not worth wasting time trying to debug it... Just swap it.
