On tvOS, third-party apps cannot read number key presses from a connected keyboard or remote (except inside a text field). There is also no HDMI-CEC API. Because of this, a live-TV / IPTV app cannot let the user simply type a channel number to change channels.
This excludes a large group of users, especially older people. They have used numbered channels for their whole lives — they remember that a given number is a specific channel and just want to press that number to get there. It is the simplest and most familiar way for them to use a TV. Making them navigate an on-screen grid with the Siri Remote instead is much harder and unfamiliar for them.
Please give apps a way to support numeric channel entry on tvOS — for example by letting apps receive number key presses (0–9) from a connected Bluetooth keyboard/keypad without forcing a text field, or by exposing the numeric keys from the TV's own remote via HDMI-CEC.
Other TV platforms already pass number keys from the remote to apps, so this works for them today. tvOS does not, which leaves these users without a basic, expected way to use their TV.
