Troubleshooting

Modal not appearing

Check that the visibility variable is properly set and the modal is not hidden behind other elements.

Modal not closing

Verify that close actions properly update the visibility context variables.

Overlay not working

Ensure the modal overlay is properly configured and not conflicting with other UI elements.

Mobile display issues

Test modal sizing and positioning on different screen sizes and adjust accordingly.
