How to Fix Power Apps Combo Box Not Working in Microsoft Edge
Question details
The user needs to troubleshoot and fix a Power Apps combo box that is malfunctioning specifically within the Microsoft Edge browser.

- Product
- Microsoft Power Apps / Microsoft Edge
- Device & OS
- not provided
- Scenario
- Operating a Power Apps application within the Microsoft Edge web browser.
- Observed behavior
- The combo box fails to function correctly and displays an abnormal inner box in Microsoft Edge, despite working perfectly in Google Chrome.
Ensure you have saved any recent configuration changes in your Power Apps session to avoid data loss before closing tabs or clearing your browser's cache.
Troubleshoot Microsoft Edge Cache and Updates
Test the application in an InPrivate window to determine if cached data or extensions are causing the combo box issue, then clear the browser data accordingly.
Often, browser-specific rendering issues with Power Apps controls are tied to outdated cache files or conflicting browser extensions. Isolating the environment using InPrivate mode can quickly identify the culprit.
Launch Microsoft Edge, click the three-dot menu in the upper right corner, and select 'New InPrivate window'. Alternatively, press Ctrl+Shift+N on your keyboard.
Log into your Power Apps account within the InPrivate window, open your application, and test the combo box. If it functions normally, the issue is likely due to your browser cache or extensions.
Return to your normal Edge window. Go to Settings > Privacy, search, and services > Clear browsing data. Select 'Cookies and other site data' and 'Cached images and files', then click 'Clear now'.
Navigate to Settings > About Microsoft Edge from the browser menu. Allow Edge to check for updates and install the latest version to ensure full compatibility with Power Apps.
Review Control Configuration and Seek Community Assistance
If browser troubleshooting does not resolve the behavior, verify the combo box configuration and consult the Power Platform Community for advanced support.

Frequently Asked Questions
Why does my Power Apps combo box work in Google Chrome but not in Microsoft Edge?
This discrepancy is typically caused by corrupted cache files, outdated cookies, or specific browser extensions installed on Microsoft Edge that interfere with how Power Apps scripts render the control.
How do I know if the problem is my combo box configuration or the browser?
If the combo box fails to display items or shows formula errors across multiple browsers like Chrome and Edge, the issue is likely tied to its property configuration in Power Apps Studio. If it only fails in one specific browser, it is a local browser issue.
Can I reinstall Microsoft Edge to fix persistent control issues?
Yes. If clearing the cache, updating the browser, and disabling extensions do not resolve the issue, you can repair Microsoft Edge via your Windows system settings (Apps > Installed apps > Microsoft Edge > Modify > Repair) to fix deeper browser corruption.
