Blend tool with Freeform Gradients does not working properly
Blend tool not working with shapes that contain gradients. (preview box is greyed out as well)
It won't work from the start with shapes that already contain gradients and only produces black shapes and an error message when the color is applied after making the blend.
I make an object and fill it using Freeform Gradient. Then I duplicate it, move it and select both objects. When I go to menu Object > Blend then the "Make" option is greyed. The same steps work fine with linear or radial gradients.
Note : Using Object >Expand Appearance shows "Non-Native Art" in the layers panel.
