The issue I’m having is when resizing on desktop it seems that the responsive works, however when viewing the site on my phone it is not responsive (columns aren’t condensing). I’m using a Pixel 3. A friend with an iPhone says it is working properly.
I tried tweaking mobile breakpoints to no avail. There seems to be a flaw in how it is handling breakpoints.
