Unable to sync between iD and iC

So, we bought this CC-solution for a year ago so that we would be able to actually use the cloud for something more than backup storing. We wanted to be able to create a workflow between writers and designers, where we could use assignments even if we sat in different locations, which we do all the time.

First you couldn't share files. Now, when you can, we are unable to create this workflow since it will not sync .idlk-files. Do you have any plans on fixing this? I mean, wasn't this the actual function that CC Suite would have? As of now, we are working with another solution so this question is more out of curiosity and a fraction of frustration.
