Creative Cloud Library changes the tracking values in character styles
Character styles added to a Creative Cloud Library in Photoshop, when viewed in XD, have the tracking/character spacing values rounded to increments of 10.
For example, in Photoshop, I added a character style to the library. This style had the font tracking set to -15. But when i open the library in XD, the style has the character spacing rounded to -20. If i add a style with tracking -14, it shows in XD as -10. If you inspect the library style in photoshop (and Illustrator) the correct value is shown.
I can apply the style in XD and then manually change the character spacing to the correct value using XD's text controls, but XD converts the character spacing of every character style in the library to increments of 10.
EDIT: I made a mistake in the original description. Tracking value of -16 rounds to -20, and -15 rounds to -10.
