On Apple TV can’t sign on to BritBox with pre-existing ID
I have a BritBox subscription I purchased on my computer on the BritBox website. I downloaded the app to my LG tv and logged in with the ID and password obtained directly from BritBox. In a different room on an older Samsung TV, I can not download the BritBox app, so I connect to my Apple TV to get BritBox on the Samsung. The problem is the BritBox app in Apple TV makes me buy another subscription through Apple after a seven day trial. It doesn’t allow me to log in with my already existing ID I obtained directly through BritBox. Is there any way around this?
