Microsoft forces you to use your Microsoft account to use it, then never keeps you logged in long enough to get notifications. Sharing via text feels like I'm back on my Droid phone, and trying to get updates to shared lists suffers from the forced log outs as well. Also can't customize "smart lists" that are stuck at the top. My Day and Tasks? That's the same thing for me, either let me put it at the bottom or let me remove them. Microsoft took Wunderlist and ruined it.
