I discovered the same issue yesterday. I tried contacting LG, leaving my number for a call back, but I never received a call. I contacted SLING, and they said they had not heard of the problem. Further, they stated it could not possibly be due to their app; it had to be an LG issue.
Is anyone aware of a resolution?
This SlingTV loop is driving me crazy. What’s the best way to contact support so they know others are having the same problem? If it doesn’t resolve soon I’m going to ditch sling and try YouTubeTV.
