Cannot Access SEC Network using ESPN app

I’m having the same problem.  I can watch the ESPN channels through the Watch ESPN app, but I cannot watch the SEC Network or SEC Network+ channels through the app.  The error I receive is “This channel is not part of your TV package.”  I do subscribe to the SEC network; I’m watching it right now through my TV.  This problem just started the last few days.  Up until then, it worked fine.
