The app would change the date, when it would supposedly arive. I understood why it wouldn't over the weekend because of the snow store. However it told me it would arive before it hit, then didnt, and then said it would arive on the 15th on the 12th. Changed to the 14th on the 13th, changed back to the 15th on the 14th, and when I first got on it said it would arise the 16th then changed to the 11th
