There are many streaming services to pick from such as Netflix, Amazon Prime, Hulu, or Sling TV, for that matter and you can enjoy them without a traditional cable subscription. That’s the beauty of it.

Sling TV offers a large selection of channels to choose from and it does not limit you to watching content on your TV. You can do it from any other device including your laptop, Xbox, mobile phone, and so on.

But there are occasions when the Sling TV app might return an error message (or more). For instance, you might come across sling tv authorization error 8-12.

Check out the steps listed below to resolve the issue.

How do you fix a Sling error 8 12?
