Which tool finds and fixes accessibility issues in a canvas app?
You are building a canvas app to allow users to record their expenses. The app also will support screen readers for users with visual impairments. You have the following requirements: • Use a tool that identifies potential issues. • Use a tool that provides suggestions for modifying the app. You need a tool that meets the requirements. Which tool should you use?
Community Insight
The question tests which Power Apps Studio tool diagnoses accessibility problems and recommends fixes; the trap is choosing Flow Checker simply because it is another in-studio checker, when it only validates Power Automate flows.
A canvas expense app that must support screen readers needs a tool that both detects accessibility problems and suggests fixes — that tool is the Accessibility Checker in Power Apps Studio. This page confirms why option D satisfies both requirements while Flow Checker, Trust Center, and the admin center do not.
Learners often pick Flow Checker because it is the only other built-in checker they remember, but Flow Checker validates Power Automate flow logic and never inspects canvas app screens, control labels, or screen reader properties.

Expert Analysis
Why the Answer Is Correct
The scenario requires one tool that both identifies potential issues and provides suggestions for modifying an app that must work with screen readers. The Accessibility Checker in Power Apps Studio was built for exactly this: it scans each screen of the canvas app for missing accessible labels, poor color contrast, missing tab order, and similar problems that block screen reader users. For every issue it finds, it explains why that control is a problem for users with a specific disability and offers a suggested change. That covers both stated requirements — detection and remediation guidance — for the expense-recording app, so option D is correct.Why the Other Options Are Wrong
Flow Checker only validates Power Automate cloud flows: it reports errors such as missing connections or malformed expressions in a flow, and it has no visibility into canvas app screens, control names, or accessibility properties. Microsoft Trust Center is a public portal for compliance, privacy, and data-protection documentation, not a design-time tool that inspects an app. Microsoft Power Platform admin center is where admins manage environments, licenses, capacity, and policies — it governs the tenant, not the accessibility of individual screens. None of A, B, or C can identify accessibility issues in a canvas app or suggest how to fix them.Community Comment Notes
Bangarng answered simply that the Accessibility Checker is correct and linked the official Microsoft Learn article on the canvas app accessibility checker. Webcreator likewise chose D and described the checker as a tool designed to flag accessibility issues and suggest modifications for users with disabilities. Astone quoted the German documentation, noting that the Barrierefreiheitsprüfung "findet nicht nur potenzielle Probleme mit der Barrierefreiheit" and also explains why each finding matters and how to resolve it. No commenter argued for Flow Checker, Trust Center, or the admin center.Official Reference
Exam Strategy
Scope the tool to the object: anything about app screens, controls, labels, or screen readers belongs to Power Apps Studio tools such as the Accessibility Checker, while anything about automations belongs to Flow Checker. PL-900 frequently tests this Power Apps versus Power Automate versus admin center distinction, so read the noun in the requirement before the verb.
Frequently Asked Questions
Why is Flow Checker wrong for accessibility issues in the expense app?
Flow Checker only validates Power Automate cloud flows, so it cannot inspect canvas app screens, control labels, or screen reader properties.
Does the Accessibility Checker fix accessibility issues automatically?
No. It lists each issue with an explanation of who it affects and a suggested fix, but you must apply the changes yourself in Power Apps Studio.
