Why can't the font leading and size be adjusted to anything other than the default sizes in Photoshop CC 2018? No change in text size if I go from 72 pt. to 100 pt. Same holds true for line spacing... can't go from 72 to 90. Why?
You can change them, but there is a bug in the current version (v19.0.1 r.190) that means you do not see the change on screen until you press the enter key. Adobe are aware and are working on a fix, see link below:
