Looking for help... I'm still learning how to use Affinity Designer and am taking online classes. The task is to take 2 objects and merge them into 1 object by using the Add feature under Operations. For some reason it's not working. The toolbar items are not grayed out before I select my 2 objects and when I try to click the button, nothing is happening. I also cannot seem to customize my toolbar... that option is grayed out. Any ideas??
