Open the Illustrator file shared with you. If the file contains fonts missing in your Illustrator app, you get a Missing Fonts dialog with the list of missing fonts:
- If you see a selected checkbox next to a font, it indicates that the font is available in Adobe Fonts.
- If you see Preview only and a greyed-out checkbox next to a font, it indicates that the font isn't available in Adobe Fonts and can only be previewed.
