Can I increase custom font size in Adobe Express Webpage? Can't seem to do this!

[Charlie23512862uf59]

I'm creating a quick landing page and have created a custom Adobe Express Webpage template. I've applied and linked Adobe fonts (Fat Frank typeface) but can't seem to increase the size of this within the template settings - its pulling through really small and scaling down further for mobile. Can anyone advise if/how to do this?

Seems like it should be a really straightforward thing to do but i can't find any results online that resolves my issue.

Have you been able to solve this?

If not, when you select the field on the canvas, is there a "lock" icon in upper left corner? If so, try clicking the icon to unlock.

HTH,
