HI @CopperCauldronArt!
What exactly did you do to solve this? I am having the exact same issue installing a web font licensed from myfonts.com.
Did you just paste the @import url line in to the code injection Header field? Did you have to include anything else before or after it in the code injection field? Or just the text provided by myfonts? This is mine -- @import url("//hello.myfonts.net/count/3b882c");
Did you then delete that line from the CSS editor completely, or leave it there? I've just tried doing this after reading your post, but it's still not working for me :(
Thank you in advance!
