APPLE TV+ ON MULTIPLE TV'S
Hello, I can only watch Apple TV+ on two devices, one TV and my iPad. From what I am reading online, you can watch on 6 different devices. The TV I watch it on is a Smart TV and then the iPad. The other TV's are smart TV's, when I launch the app on the other devices, it looks like it will start and then the screen stays black with the Apple TV+ logo, and nothing else happens.
How can I correct this? I love the series and movies that have to offer.
Thank you,
Nancy
