Apple TV subscription not working on second TV
I have an Apple TV subscription through Barclays and I am signed in my account on 2 TVs in my household. However I am only able to watch Apple TV on one of the TVs but not the other.
Whenever I try to select a show to watch, it asks me to subscribe or start a 7 day free trial. I've checked the membership / subscription section in my profile on the TV and it definitely says I have an active subscription so it's very frustrating why it isn't working.
I have signed out and back in several times but it still doesn't solve the problem. I am not trying to watch on both TVs simultaneously just in case that causes a conflict, which it shouldn't anyway as apparently I can share the subscription with up to 5 family members.
Can anyone help on how to fix this please?
TIA
Steve
