I’ve never come across this issue before - working on a new site that uses the stock Lato font family, on my homepage I can access Thin, Light, Normal and Black but on any other page I can only access Normal and Bold?
Don’t feel bad… my most embarassing questions, I usually ask them directly to support@webflow. I think the last one was “Why is there suddenly tons of cookies and trackers on my websites?”, when I was (obviously) visiting them while connected to my account…
