Download tab not working

On the Xfinity stream app, I can download, watch, return…but the downloads tab/page is not working.  It’s dead, blank.  My downloads aren’t in the phone but not on the downloads page.  So, I can watch downloaded shows from the ‘recordings’ tab.  HOWEVER, the ‘recordings’ page/tab goes dark when I'm

offline (as it should)…but the downloads tab is dead.  So I can’t watch anything when I’m offline.  Help!
