Hello vernpreacher,
To help resolve this issue, start by resetting the Apple TV app:
Get the Apple TV app or Apple TV+ app on your smart TV or streaming device - Apple Support
Reset the Apple TV app or Apple TV+ app
Resetting the Apple TV app or Apple TV+ app removes your personal information and restores the app to its original settings. If you plan to sell or give away your device, or uninstall the app, you might want to reset it first.
1. Open the Apple TV app or Apple TV+ app.
2. Go to Settings.
3. Choose the Reset option.
If you lost or can't access your device but are still signed in to the Apple TV app or Apple TV+ app, remove the device from your Apple ID device list.
If you reset the Apple TV app or Apple TV+ app on a smart TV that's also signed in to the Apple Music app, the Apple Music app restores to its original settings.
On Amazon Fire TV, Android TV, and Sony TV devices, you can't purchase content from the Apple TV app. You can buy, rent, or subscribe on another supported device and then watch in the Apple TV app on your Amazon Fire TV, Android TV, or Sony TV device.
You can only watch the seasons of shows when they become available on Apple TV.

Best Regards.
