Just exported a fairly simple frame. Lines of text were multiple lines, broken within lines, and within words. Shapes, like circles, were turned into line segments and strokes were separate from fills. Shapes where embedded in clipping masks that had no visual effect.
I need to clean up Miro files for presentation, since it lacks decent control on curved lines, text control like padding and margins and tools to get more than basic alignment. So, since I can’t get those capabilities within Miro I would like the resultant PDF to be as clean as possible so that I need to do as little clean up as possible to style the result.
