I was having a VERY hard time with Adobe XD finding the fonts I activated with FontBase, BUT I have found the unusual solution to fix that problem by simply —
- Go to Settings (it should be a vertical ellipsis "…") in FontBase
- Change the Root folder location to "C:/FontBase" (or C:\FontBase — not sure if it's front or backslash)
Very strange that Adobe XD didn't find my fonts to the default location FontBase put it (originally located in "C:\Users\%PROFILE%\FontBase"), so changing that location solved my issue.
Hopefully, this helps a lot of you out there!
