Hi there, I noticed an odd bug on the latest version of AD for Windows.
If you have a shape (or pen shape) which has a gradient stroke and you copy it and the paste the style on another shape (ctrl + alt + v), it will copy over the stroke gradient. But if you then click the colour swap (so the stroke and fill properties switch values) then the shape will be filled as one of the colours, rather than a gradient.
Cheers.
