Hi xanda, Im not sure if you left the partial quotd out?
I can't see how one of the previous posters lost his channels after an update....unless it was not a 2019 set. As I stated on Facebook, they should have a disclaimer on the box, or inform the sales outlet that these sets are not capable of receiving the channels, giving the customer a choice to buy it or not. After all, the only reason I bought a new tv for a different room, was so I could watch these channels. The UM74/UM70/UM76 models are ones I know of, that do not have the capability to receive these channels.
