Does Optimole work on websites that have not been pushed to live yet?

Hi,
I am developing a WP website which has not been pushed to live yet
I installed Optimole in order to have the pages, that are partly done with WP Bakery Page Builder, to scroll at a normal speed

Optimole seemed to work at first but now I get the same issue that I had before activating this plugin (that is slow scrolling on some devices when testing the website with Chrome dev tools). I left Optimole default settings

On the Optimole Dashboard I get:

“Last optimized images

We are currently optimizing your images. Meanwhile you can visit your homepage and check how our plugin performs.”

This message has not changed since I activated Optimole

Let me know, thanks
Best regards,
