I'm currently unable to upload images to other hosting services and include them in this comment. The problem is very simple: when I select some text and click on the "Typography > Select Font" menu, in the pop-up menu that opens, if I select "Extra Light" or "Light" or "Normal" in the "Weight" drop-down menu, the changes to the text aren't applied.
I should also add that until yesterday I could access the "Layout Packs," but now when I click on the "Layout Packs" menu, the menu with the available layouts doesn't open; instead, I get a gray screen with the upload loader.
