Fonts (Figtree Light, Regular, and Bold) would not appear in Illustrator dropdown after I activated them either in Illustrator's Adobe Font Search feature, or on the Adobe Fonts website. Closing the file didn't work, closing and restarting the program didn't work, restarting my computer didn't work. I followed a help document to figure out this workaround: Turning off the entire Adobe Fonts service in the Creative Cloud app, then turning it back on. This did solve the problem for me this time, but it's a workaround for a broken feature. It is also time-consuming. It means that a core service Adobe offers, Adobe Fonts integration, is severely buggy on my modern Windows 11 system. If the feature doesn't work, it should be fixed or removed and replaced with a functional workflow.
