For the last two weeks (Feb 2020) TV guide time has been EST instead of Pacific time zone, how do I change it back to Pacific time zone.

Same issue here in AZ. Very frustrating. Spent so much time trying to resolve and no one has a solution. They told me a week or so ago that they were working on it and it should be resolved within a few hours. Hahaha. A week later and nothing has been corrected.
