Mobile not rendering Plasmic Studio designs full width?

Has anyone dealt with mobile not rendering plasmic studio designs in full width?

For example, our design is fully width in plasmic studio.

On mobile, the page renders with a blank white column to the right.

This page was made using figma import, so it consists mainly of free boxes.

I have double checked every free box and ensured the width is set to stretch.

The issue is isolated to mobile only.

Hopefully, I’m overlooking a tiny setting. Any suggestions would be greatly appreciated

Usually this is due to some element on your page being wider than the mobile screen width

One way you can find it is to keep deleting things until the preview mode stops doing that (you can pop out a preview window)
