Keeping with the theme of this post, I’m updating it with a workflow problem brought up by another user.
6. Projecting onto a Sketch
Before the update, Sketches mingled together, for good or bad, but this meant that you could combine them as and when you needed to. Now if you project onto a Sketch, it no longer interacts with it and behaves as a separate Sketch.
Workarounds here: Projecting
The workaround works, but it’s definitely a workflow disrupter if you rely on it regularly. And then you have sketches on top of sketches which adds to the confusion.
