No longer able to stream local channels - DirecTV

A couple of weeks ago my channel list changed when streaming live TV on a tablet, in my home. I have had the dish since Oct and successfully streamed local channels until early Dec. Now my channel list starts at 200 and I can't see any channel below 200. Has there been some change that wasn't announced in the live streaming offering?

This question, "No longer able to stream local channels," is about DirecTV channels, programming, equipment, and sports.
