Directv Roku App no longer has a key to go directly to guide

The Directv Roku application used to go directly to the guide when selecting the down arrow while watching.  They did an update some time ago and the key no longer worked at all.  The "Fix" was to make the down arrow go directly to the menu like the "Back" button does.  So now with the minimal keys that exist, 2 keys do the same thing and no key goes directly to the guide.  Just sill and I would say a design flaw except it used to work.  Now it's a bug.
