Solution of Apple TV+ unable to play problem

I have a problem that the content I bought cannot play. I called the customer center, but they also couldn't find a way to solve the problem.

More than 800 people have the problem, but Apple can't tell you how to solve it.

I have found a way to solve the problem, and I would like to share it.

1. Download the Apple TV app to another Apple device (iPhone, etc.).

2. Play a little bit of your purchased content on your Apple device.

3. Play the content you bought on the TV.
