Streaming live at 10am (PST) site looks very different than when published to my domain

I’m hoping someone might be able to help me!

While designing, I constantly published my drafts on my default site so that I could test on my iPhone and browser. Now I’ve run into the issue where I’m v happy with my site, but it looks tiny and scaled down (on mobile) when published to my domain. Both versions looks similar look and work the same in my browser. I’m using Webflow to host, and publishing them at the exact same time, but seeing different results. I’ve attached screen shots for reference. If you have any ideas, I would be so so grateful! Thank you

Here is my site Read-Only:
