I've seen this at least twice ... The connect app will correctly record my steps for the day in the steps view but stop updating the weekly challenge steps at some time (anywhere from 3 to 12 hours, I dont know exact time) before midnight local time on Sunday. The challenge board will report that a few hours remain to the challenge, based on the local time when midnight Sunday is to occur, but steps stop incrementing on the challenge board. The "final" tally / scoreboard order the following day reflects the at which steps stopped being updated in the scoreboard.
Is this a known issue or bug? Or is this somehow considered correct behavior? It's a little de-motivating to think that the steps I record after an unknown time Sunday won't appear in the scoreboard ...
