Cannot log into Apple TV with Fire Stick
Receiving error N/645416E6 when I try to log into Apple TV using a Fire Stick on a Samsung smart tv.
Have tried the following:
- Verified Apple ID and login. They work.
- Restarted Fire Stick.
- Cleared Apple TV cache.
- Cold started tv, unplugged and plugged back in.
- uninstalled and reinstalled Apple TV.
- verified Apple TV subscription is available.
- Can log into Apple TV on another device.
Windows, Windows 10
