Troubleshooting common issues with screen size detection and testing.
🔧 Steps to Adjust Font Size Based on Screen Size:
1. Add a label to display the screen size using `app.activeScreen.size`.
2. Observe how the size value changes with different screen widths (1 = small, 2 = medium, 3 = large, 4 = extra large).
3. Set conditional font sizes for labels within the gallery based on this screen size value.
Example: If `app.activeScreen.size` is greater than 2, set font size to 13; otherwise, set it to 11.
4. Apply similar conditions to headers for consistency across your app.
5. Optionally, refine the formula to handle additional conditions for even smaller screens.
💡 Helpful Tips:
The screen size value may not update accurately in Play mode. Test using actual device dimensions or browser inspection tools.
Adjust the size breakpoints in the app properties to customize how screen sizes are classified.
