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
✓
Check for an updated version of the custom visual from the developer.
The correct option is C: check for an updated version of the custom visual from the developer. Custom visuals from AppSource are third-party components that can break when Power BI Desktop updates change the underlying rendering APIs, so the developer typically publishes a compatible update that resolves the rendering issue. Option A is not a real Power BI feature for custom visuals, and compatibility mode applies to semantic model/version settings, not to fixing a broken visual. Option B would discard the intended custom functionality rather than fix it, and option D merely re-adds the same outdated version, so the problem would persist.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable compatibility mode for the visual.
Why it's wrong here
Power BI does not expose a 'compatibility mode' for custom visuals. This setting does not exist in Power BI Desktop, the service, or in the visual itself. Enabling it would be impossible, and the option merely confuses troubleshooting with a feature that is intended for other scenarios, such as legacy report compatibility. Since there is no such toggle, this step cannot resolve the rendering or loading issue.
- ✗
Replace the custom visual with a built-in visual.
Why it's wrong here
While replacing the custom visual with a built-in visual might allow the page to render, it abandons the custom functionality, data mappings, or formatting that the original visual provides. Built-in visuals are not feature-equivalent and may require you to redesign the report, losing the specific insight type. This is a workaround that changes the report's content rather than fixing the underlying incompatibility, so it is not the correct troubleshooting step when a custom visual fails.
- ✓
Check for an updated version of the custom visual from the developer.
Why this is correct
Custom visuals rely on the Power BI visual API, and when Power BI releases a new version, previously certified visuals can become incompatible. Developers routinely publish updated versions of their visuals to align with the latest API changes and fix bugs. Checking the AppSource source or the developer's website for an updated version is the recommended first step because it directly addresses the root cause of the incompatibility, often resolving the issue without altering the visual's functionality.
- ✗
Remove the visual and add it again from the marketplace.
Why it's wrong here
Simply removing and re-adding the same custom visual from the marketplace will not change the version you are using. If the current version is incompatible with your Power BI environment, reinstalling it retrieves the identical payload and the same error will persist. This step only works if the marketplace offers a different, newer version, but at that point you are effectively checking for an update—which is the correct action. Without a version change, this is a non-fix.
