Is anyone able to add a node (using the Node Edit tool) to a Bezier shape in a group?
yes, click (twice) into shape into group and add a node
Does not work if the shape is in a group. I have tried multiple ways and only means of adding a node is to remove the shape from the group, add the nodes, then return to the group.
I contacted support and it is a known issue. They are working on a fix.
