Actually, a lot of the functionality that has been broken in previous builds had finally made a comeback. I can finally set reminders, play my music, and much, much more that I couldn't do before. Reading and replying to messages was on the top of my list of what I wanted, though.
On the down side, this build seems to have broken a number of apps, most notably games, that will no longer launch. I get a pop-up that states it can't be opened and that there may be an update in the store, but there never is.
