Hi there,
Not sure if this is a bug with the new update or if I’m missing something, but whenever I add a global colour as the BG layer upper it doesn’t allow me to change transparency. See this video of the issue: https://www.loom.com/share/df870cb0a9934c35aca0a73ebabf645e
As you can see it works with any other selected colour except global.
Cheers,
David
