Tonight when I got home, I tried to update the Sling app to the Fire Stick. I went to Live TV as usual, clicked on the services to update. All worked out fine, except for Sling. The 600+ channels (Sling Blue+Free), will not add to the Fire TV guide tonight. I checked for an update, and the Fire Stick had one, I took it. still did not work. I tried re-booting a few times. I even took Sling out and reinstalled the app, signed in and Sling works fine, but again, it will not add the channels to the Fire Stick guide. Is anyone else having the issue? I had this with Plex a few months ago and finally after a couple of weeks, I found the Plex channels back in the guide. Thanks.
