Sorry missed your last question, It has a live tv button but it is linked to the apps and bbc do not play nor do Channel 4, it’s a bit pointless really lots of amazon tv channels.
Freeview isn’t an official app on firesticks.
you have 2 options depending on what you bought the firestick for:
1 – Sideload Freeview onto the firestick effectively jailbreaking it (cough) and download the appropiate ipk(s).
2 – Do what Marc has done.
