I think you mean BT Packages(?) If you’re receiving BT Sport via Sky, the “flexible TV” option is not available on your Sky box. You have to buy the BT box. It’s a ruse to tempt you to ditch Sky, and receive any Sky packages via the BT box! I can’t say for sure, but I have the distinct impression that the “turn on and off -able” element isn’t as “flexible” as it sounds. The TV ad implies switch “for a month”. So either way, channel on or off, you can only make one switch per month. Much better than Sky, but far from perfect IMHO.
