Hi Sharon
Frustrating though this has been I detailed my solution on another thread...
"Managed to find the root cause of everybody's problems: site https://appleid.apple.com/ is where u manage your Apple ID. Here the terms and conditions are downloadable as PDF's but there is no feature that allows u to accept T&C. What I did as someone who does not own any Apple products is use the site to create my ID. Apple TV is different in that it is a software product that runs on various non Apple platforms.
What the good folks at Apple have presumed is that you own Apple hardware and have used its supporting app which allows u to agree T&C hence the lack of feature mentioned above. All Apple have to do is add the feature to its maintenance site which brings with it platform independence.
I downloaded the Apple Music app from Play Store on a Samsung tablet entered my ID completed what was required including agreeing T&C then on a windows laptop logged into Apple TV to complete my subscription. Then I uninstalled the Music app. So the bunny is happy; watched two episodes of Foundation and will buy the 12 months subscription when the 7 days free trial ends and all without owning any Apple products.
Hope this helps."
Sorry but I don't know to provide you with a link to that thread.
