I wish I could remember what mine did last year. All I have is that I filed on the 31st and my refund was deposited on the 15th. I can't remember what WMR did in terms of updates.
This year I filed/accepted on the 4th, but it hasn't updated to anything other than the 1st bar and saying most refunds are issued within 21 days if all is correct blah blah blah.
And I will reiterate again, it says they can't legally issue refunds UNTIL THE 15TH, not the end of the month. It says that you may not see them until the end of the month because you know they're the government, but you can also possibly see them the 15th.
