6. Adjust App Permissions:
- Go to your Settings again.
- Tap on Apps, then select MintAI.
- Ensure that the app has the necessary permissions, especially access to your photos.

7. Try Enhancing Different Images: Test the app with various photos. Sometimes, the image format or size may create issues.

8. Use Remote Images Setting: Some users have found that changing the settings to prefer remote images helps. Navigate to the app settings and look for options related to image sources.

9. Uninstall and Reinstall the App: If none of the above steps work, uninstall MintAI and then reinstall it from the Google Play Store. This can solve the problem if the app's installation is corrupted.
