Did you try deleting the Data in the APP and restarting ?
Just followed those instructions. After restart or force stop, the guide will refresh. I'll look at it again in a couple of hours to see if it is automatically refreshing now.
Waited a couple of hours after clearing the data from the app and rebooting. Initially, the guide went from 3:30 to 3:30. Now it's from 6:00 to 3:30.
