Why I am unable to click on 320 responsiveness?

Hey all, I just started working on bubble.io couple of days ago, following some video tutorials to get myself started, but on the video I am watching, this person clicked between 320/768/992/1200 to see how the app responds on those sizes.

For some reason, I am not able to click to preview 320 version. All the other sizes work fine, and I can click on them, but not on 320.

Could anyone help please? Anything I need to do in settings, or? Attaching image.

Hi there, @housecoginfo… on the Layout tab of the edit dialogue for the page, do you have a Min width set for the page? If so, remove the min width (or set it to a number so that 320 becomes a viable responsive option) and see if that does the trick.

Best…
Mike
