Testing the Waters: Why Power Apps Preview Isn’t Always Ready for Prime Time

Preview features are early releases provided to allow developers and organizations to explore and test new capabilities before they are fully supported. These features may change, have limited documentation, and are not recommended for production environments. In contrast, GA features are stable, fully supported by Microsoft, and ready for use in live environments.

Key Points About Preview Mode

1. Early Access Feature

Microsoft releases features in Preview to allow developers and organizations to try them before general availability (GA).

2. Not Fully Supported for Production

• Preview features may have bugs, performance issues, or missing functionality.
• Microsoft does not guarantee full support if these features cause issues in production apps.

3. Subject to Change

• Features in preview can change significantly before general release.
• Certain properties, behaviors, or APIs may be updated or removed.

4. Feedback Opportunity

• Microsoft collects feedback from early users to improve the feature before GA.
• Using preview features in non-production environments is recommended for testing.

5. Common in Power Apps

• Examples include Modern Controls, Virtual Tables, or Co-Pilot integrations before GA.
• In your case, the modern dropdown is still in preview mode, which is why it may not behave consistently inside a gallery.

• Use Preview Features only in Dev/Test environments.
• Avoid in production apps until they are GA (Generally Available).
• Always monitor release notes to track updates or changes to preview features.
