I believe the Lightroom Mobile workflow is designed to work differently than you are expecting it to work. Lightroom mobile synchronizes with the images that are on the main computer. Any adjustments made using Lightroom mobile will be synchronized with the master photos. The master photos that reside on the main computer are the ones that really matter. The files in the cloud are simply copies that are there to enable mobile editing.
Interesting, but the value of this use case is not obvious to me. Should I really adjust my workflow to a tool or should a tool rather deliver a solution to common problems (like taking bulky computers to travels definitively is). Traveling=Photo taking=Using mobile devices... While a workflow for traveling with a camera and just an iPad would be indeed very useful, working with fotos on a mobile device that are already on a repository seems a rather rare use case to me. Why should I do that? Editing on a computer works just so much easier and precise. My conclusion, to be honest: Instead of using the chance of providing a real killer application for travelers, the app just provides more or less a viewer to a library existing somewhere else.
And technically, why this restriction? LR is well known for its RAW workflow and this is heavily used. RAW on iPad is possible, as other software proves. So is it a marketing decision not to support it?
Maby the app could just support different workflows, including the one that would really make a difference for people on the road?

It's not obvious to a lot of us - but nevertheless, that's what's on offer. Whatever Lightroom Mobile is, it isn't a mobile Lightroom.
I have been waiting for this as well. Apple and Adobe, please make it possible.
They made it possible over a month ago....
