MY MacBook screen mirroring to my Apple TV stopped working a couple weeks ago. Only shows black screen. Help

Hey PatrickVMI1999,

You found the right article to start troubleshooting. Were you able to work through the suggested steps?

If screen mirroring or streaming isn't working on your AirPlay-compatible device - Apple Support

• Update both your Apple TV and your MacBook to the latest tvOS and macOS versions.
• Restart all three devices (MacBook, Apple TV, and your actual television).

This is also a great resource:

Use AirPlay to stream what’s on your Mac to an HDTV - Apple Support

• Your Apple TV and MacBook need to be on the same Wi-Fi network. If you have a router that gives the option for different bands, make sure they're on the same band as well.
• Set your settings to choose your Apple TV as the size as outlined in #3.

The articles we provided will help you make the changes. If you're still only seeing a black screen, try playing videos from Safari or the TV app on your MacBook. We're curious about whether this only occurs when you try to use the ClearPlay feature with Amazon.

Regards.
