Hi, thank you for the response! The button showed correctly after a newer version of the theme was installed. However, I am now facing another problem which is that my WordPress editor is not showing the right font and the “Aa” global fonts button is missing from the editor as well.
A few pages also had their paragraphs bunched up (no gaps between paragraphs) and I had to copy and paste the content into a new column to get them published correctly. WordPress Support has not been able to resolve the issue so far…
