I have been experiencing a lot of issues with my mobile and desktop site. The formatting on my desktop site is very off compared to my workspace. My mobile site always displays a white space below my footer. I have unchecked the sticky footer and have tried various things to remove it. Nothing has worked I need a staff member to overlook my website and tell me what the problem is.
The top is preview. The bottom is in my work space.
At the moment there´s no way to overlook your website without a link or a reduced to your issue .muse file, shared ivy dropbox or CC.
I see that you use system fonts instead of web fonts (this T in the left downwind corner) but this doesn´t cause your mentioned issue.
You could try to reduce the minimum height in the mobile breakpoint to, let`s say, 500. This could help, maybe without further investigation so far.
Does this help
