I see that the Omni-Channel Implementation link actually works from the list on the left pane of this group, but under "Known Issues - Fixed" for Summer 15 they state that the links to the Implementation & Dev guides (within the Omni Channel setup screen) have been fixed...but they don't appear to be, still get an invalid redirect error for both.

Can someone tag the proper resource to alert them? The links they provide in the "fixed" page also give an error :)
