I was experimenting with the PDF drawing tools on iOS, and discovered that I couldn’t find a way to erase a shape after it was drawn. E.g., if I draw a rectangle, the eraser tool does not seem to remove it. Undo was the only option I could find, but of course, that only works if what you want to undo was done recently.
Is there a way to erase or delete shapes (unlike pencil drawings)? Maybe I just haven’t found it.
