Big10 Network frozen on To-Go stream

We are out of our home area for the winter trying to stream the Big10 Network on our I-phone and I-pads.  The channel is in our Available out of home (TVGO) channels.  However each of the three available channels are frozen on the same screen when we click on Watch.  It's the same frozen screen of 3 men on what looks to be an episode of BIG 10 TODAY.  We have tried again the past three days and get the same results.  Last year when we were here we had no issues streaming this channel.   Is this a BIG 10 network issue or Xfinity Streaming issue?
