When I select 'Start Global Edit' I get a message saying, cannot find similar objects, adjust filters and try again. I have attached a screenshot, showing multiple images of a horse, which I want to edit. I do not know how to do this. Grateful for any advice.
The groups will need to have the exact same structure in all the copies. Same stacking order etc.
But on top of that, I have seen Global edit fail with much simpler objects. If e.g. pixel snapping is turned on, you might get some minor changes in your objects with each copy and then Illustrator will not recognize them anymore.
