It is both an accessibility and usability issue because it affects all users.

It is a usability issue because it affects all users, not just those with disabilities.

It is an accessibility issue because users with disabilities are included in the test.

It is neither an accessibility nor a usability issue because the feature is new.

Automated tools are only useful for compliance reporting and not for finding real issues.

Automated tools should be used after manual testing to confirm findings.

Automated tools are useful for finding a subset of issues, but manual testing is needed to evaluate usability and complex interactions.
