Hi Shabdeh,
Welcome to QSM Pro Support.
I tested QSM with Elementor on my localhost. And everything worked fine on my localhost. Here are the things I noticed when used QSM with Elementor.
1. Paste the quiz’s shortcode in the Elemmentor using Shortcode module.
2. Then, click ‘Apply’ -> ‘Update’ button to apply the shortcode in the page.
3. Now if you preview the page, the quiz will work perfectly. And if you see quiz numerable times on the Elementor editing page, just refresh that page and you will see the quiz as perfect as on the preview page.
Kind Regards,
Kriti
