I downloaded version 17 of InDesign this morning. The second existing file I opened to work on, I got the Type 1 end of support message. Have not gotten this message on previous versions and did not get it on the first file I opened that uses the same exact font set as the first. I went to the Find Fonts window...it says "Type 1 fonts 0" Checked all the fonts manual...3 are open type, all the remaining fonts are Adobe Crative Cloud desktop fonts (activated online). A bug perhaps?
