I downloaded the Apple TV app on my Amazon Fire Stick 4k. I successfully logged in using my Apple ID and PW. A Message came up stating I had 1 year free subscription since I had just purchased a new iPhone. All is well. I watched the first 2 episodes of The Morning Show but when I tried to watch the 3rd a Pop Up menu came up with something like " NO App purchases can be made with this device". I logged in and off several times but I could not watch any more than episodes 1-2. So the App must think this is a trial and only allows watching 2 episodes but yet when I logged in it said I had 1-year subscription. Confused.
