I’ve been using Blender for a while now and I’m using v3.4.1
when I use Alt+D to duplicate an object, when going in to edit mode the linked objects are not highlighted.
When I edit the object all the linked objects edit as expected. It is just that they are not highlighted.
This used to work so I expect I have pressed something by mistake without knowing and turned it off?
After several hours on Google I thought I would ask on here if anyone can help.
