PL-900 Demonstrate the capabilities of Power Apps Practice Question

The app maker checks the form customizations and confirms the button is configured correctly. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The custom button is configured with visibility rules that hide it for certain security roles.
Custom buttons in model-driven apps can have visibility rules based on security roles, which would hide the button for users without the appropriate role. Option A is incorrect because browser compatibility does not affect button visibility. Option B is incorrect because the button was configured for all form factors. Option D is incorrect because flow permissions affect the execution of the flow, not the visibility of the button.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The user's browser does not support the Power Apps client.
Why it's wrong here
Modern browsers are supported; button visibility is not browser-specific.
- ✗
The app is opened in the phone form factor, and the button is only shown on web.
Why it's wrong here
If configured for all form factors, the button should appear on phone.
- ✓
The custom button is configured with visibility rules that hide it for certain security roles.
Why this is correct
Command bar customization allows role-based visibility; the user may be in a restricted role.
- ✗
The Power Automate flow is disabled or not shared with the user.
Why it's wrong here
Disabled flow would cause an error when clicked, not hide the button.
