My site header font changed in desktop but not in mobile version

I used YellowPencilPro to change fonts & other items in my theme PhotoGridly. The site header changed in desktop version but I have been unable to get the change to occur in mobile. I don’t think this is a cache issue because when I go to the customizer & select “tablet, or mobiile” view, the font shows that is has not changed in those areas, yet, it does show the change on desktop when I switch views. Every other change I made has saved & displayed accurately on both mobile & desktop. The theme will not help me unless I upgrade to PRO…but this is just 1 section I want changed & that’s why I purchased the plugin “PRO” version to be able to customize my site. I have flushed the cache, viewed in incognito, tried some other codes from forums, but that has not worked for me so far. Even the other menu items in the header changed in both areas…but that site title adjustment just won’t display in mobile??? I am very beginner also!
