App did not properly import all data from Wunderlist as Microsoft claimed it would. All of my 'created dates' for items in my list got wiped amd set to the current month day and year of when I did the import a couple days ago. This would seem to be a simple table record to grab from the Wunderlist database, to transfer over to To Do. I would expect a cleaner and better QA'd experience from a company like Microsoft. This is as of build #151.
