I posted sometime back that it had been removed---it no longer worked on Roku and someone commented yesterday:
Well after several post with no resolve I simply went back to channel search on roku and "added" RT while never removing it from my lineup and it quickly installed and played back! Don't understand it but I do have it back playing. Just a goof or its been put back in. No answer but it worked and is playing just fine. Try it and post results.I did it and it worked. Thanks to the anonymous commenter!
