I have been experiencing this since at least yesterday, but vaguely remember it happening late Thursday night. I can't even reinstall on my roku because it doesn't give me the option to delete the channel. I'm glad it's not just me, though.
It started January 12 for me. I stayed up until midnight to get the next episode of “The Secret Life of Amy Bensen”. I tried deleting and reinstalling, logging out and back in. I finally had to just watch it on my phone. I emailed them and they responded quickly explaining they are aware of the situation and will have it resolved soon. It has not been resolved.
