Page ranking on mobile, but not showing up AT ALL on desktop search

Hi there,

One of my blog posts is ranking on the second page of the SERP for a particular keyword, however, it is not even showing up under results if I do the same search on desktop.

Strange thing is that it used to be there on desktop as well, it just completely disappeared from one day to the other (only on desktop though). So, not showing on ANY of the pages.

The site is couple of days old, but I cannot image it has to do with that.

Could anyone help with this please?
