I've seen some glitches with that app too, like the widget still showing yesterday's shows even the next day until I perhaps launch the app and only then it might get refreshed.Guess i'll revive this thread for a question on the newer Teevee 3... with notification widget.
One of the shows i added... "Scorpion"... aired yesterday. But it still lists it at the top of the list of shows... and instead of showing time to air (since it has already passed).. it says "loading". So it is still at the top of list, and is in the notifications widget. I have tried quitting and relaunching. No help. I also do not see how to even remove a show...
