Interesting new development. As of 3:18 pm Eastern, I can now log in to the app. And when I first went to the PVR tab, it would show me my recorded programs but not my scheduled. Then after a minute or so, it eventually showed my scheduled recordings. Though for one of them, it is displaying "Manual Recording" but when I look at that day and time in the guide, the red recirding dot is showing for the program I have set to record. I suppose it may clear up at some point.
So I don't know why it magically started to work. Maybe posting this caused some tech to look into it? I won't hold my breath over that one.
