U-verse app: Guide not loading

Have been seeing this for a few days, could have been going on longer:

App opens, seems to function, but every channel, every day, has a single program "Not available" that runs from 12:00 AM to 11:59 PM.  Tried clearing cache: no change.  Tried clearing data: no change.  (Note that while it cleared my username and password so that I had to log back in, it apparently stored my favorite channels online, because I didn't have to set them back up.)

I have the most recent version available from Google Play Store.
