The Skip a day buttons that go one day forward and one day backward on the App Sessions tab should do what they say, they should skip a day.
Instead they go to the next midnight or to the previous midnight.
It is more likely to check what happens every day during business hours than at midnight.
I wanted to see what happens every day when the shop starts working at 6 am. I hoped that clicking on Skip a day it would skip a day, instead I had to go to the next midnight, then click my way through it, then next midnight, etc.
