How do I keep only my countries and hide the rest?

Large playlists sometimes cover thirty countries or more, while most households only watch two or three. "My countries" trims the lists down to what you care about.

Steps

1. If your playlist covers several countries, the "Which countries and languages do you watch?" screen offers itself automatically when you add the playlist. Otherwise, open Settings → Countries and languages → Choose.
2. Tap each country to keep; the number of channels involved shows next to it.
3. Confirm with Show only these, or tap Keep everything to hide nothing.
4. To change this later, reopen Settings → Countries and languages.

Tip

Hiding one specific channel or category (rather than a whole country) is done with a long press on its name (the "Hide" quick menu). The list of everything hidden, with a button to show it again, lives under Settings → Countries and languages → Hidden items.
