It was working until about one week ago.  When I click on the app, a message displays "The channel 'YouTube Featured" is not available."  It does that if I am not connected to the internet.  It normally does that, but what is different is that the message pops up with a lot of lag.  It normally takes 15 seconds to pop up.  Then about 10-15 seconds later it closes the app.  If I'm connected to the internet, the app just closes in about 30 seconds.

I tried it at 4 different places, and it doesn't start up even if I'm offline.
