The PDF Accessibility Checker will help you identify and fix most other issues within your pattern, such as putting alt text onto images. You go to the Accessibility Tools,
open up "Accessibility Check," not "Accessibility Report."
From there a menu will popup on the left hand side showing every accessibility issue that needs to be
addressed. You can then, for most issues, right click on the warning and click "fix" and it will guide you through how to fix most of the basic accessibility issues.
To note, two maybe three different warnings will not go away once you fix them. That would be the warning to check the logical reading order, color contrast,
and navigation links. Thats because these warnings cannot be verified by the automatic checker, and have to be manually checked.
