Following this explanation to scale a pattern down in Illustrator 2020 doesn't seem to work.
To reproduce: Create a New Document, draw a Shape, apply a Fill color, select a Graphic style, right-click the Object, Select Transform, then Scale, uncheck everything except Transform Pattern, chose a value.
Nothing seems to happen. Alternatively it's impossible to click "Transform Pattern" without "Transform Object" becoming ticked automatically (I don't want to scale the object, just the Pattern).
I've been using Illustrator for 20 years now, so it's either a new bug or I'm missing something obvious.
