Mostly works well, but I am rather disappointed with the syncing issues my wife and I are experiencing. I'm unsure as to what Microsoft has changed from the "Wunderlist" app that I've been forced to switch from, but this app does not work as quickly and nicely as wunderlist did, which I had been using for 2 to 3 years constantly because it worked so well. Please revise this app so that connectivity problems from servers can be solved. I am unable to sync some/all of my shared lists.
