Hi, I've been seeing bugs on my site for days. The text formatting buttons do not respond correctly.
I'm not sure to understand what's not working.
Are you referring to the colours and fonts settings in the admin panel, under Design > Colors & Fonts?
I have just tried on your site and the text size, line height or letter spacing updates properly. Have you tried clearing the cache of your browser?
