Please help! I've searched all over the internet, called Adobe Customer Service and spoken to my IT guys.
Problem: I have an existing Indesign document 60+ pages that uses lots and lots of tables. Every quarter this document gets updated to reflect new figures in the tables. This time I have opened after working on it yesterday and the font suddenly acts as if it's missing??
I have since deleted the font and replaced with Futura PT Condensed. BUT now this font acts as missing also. I have deleted all duplicates, it's a font synced from Typekit. I have the most updated version of Indesign (CC), though I did try to backdate Indesign and see if it worked (it didn't). I've also tried saving as an IDML file, on a different computer in the office, an older version of the document which has worked previously and now the font acts as missing. I have restarted my computer... I tried adding the font to the "Font" folder in Indesign folders. NOTHING WORKS.
Sometimes it looks fine that the font is there, and then I go to change the leading and boom, the font goes highlight pink and replaces with some dodgy font I can't even understand and acts as if it's missing again. Then I'll move out of the document and come back and it's miraculously there again, only to disappear again 5 mins later.
You have described my exact same problem (everything shows the font is synced but indesign can't find it). It was just when I went to check CC Desktop when I saw that it was having some syncing issues. I clicked reload and magically, when going back to Id, they fonts appeared (I had 3 missing fonts!).
I was having a similar issue, fonts looked like they were open in FontBook but not available in InDesign. I usually drag and drop into FontBook, but the solution to this problem was to delete the problem fonts, add using the "+" instead of drag and drop, ignore the warning that fonts weren't loaded, and reopen the InDesign document. They are older fonts that don't have extensions as part of the font name, and it seems like this is the problem.
