If you exit the app while watching a channel and then return to that channel via the top shelf, there is no current program data in the grey info bar at the bottom, though it does show what’s coming up next. Swiping up on the remote to bring the program info bar up also yields no current program info. You must change the channel or quit the app for the current program info to be repopulated.
A small bug, but I figured you’d like to smash it.
