UI SCALING ISSUE ON 4K DISPLAY ... TOO SMALL!!
As I'm sure you're aware by now, the tools and menu links in InDesign are way too small when displayed on a 4K screen. I've just installed CC on a new Dell XPS 15 7590 with 4K LCD screen with default Windows scaling setting of 250%, which works fine for all the Adobe apps I use (Photoshop, Illustrator, Premiere, Acrobat) except InDesign. PLEASE FIX!
Exact same problem, Also on Dell XPS 15 4K Screen, other adobe apps UI scaling look fine
