Hi, to all.
Affinity Designer does not know how to ungroup SVG files. Yet it is one of the most widespread vector formats, and the only one available on Wikipedia. This means that you have to go through InkScape to be able to paste the unbundled image at the lowest level in Affinity Designer (Ungroup All)!
See this example of SVG file on which you have to ungroup several times in InScape to finally reach the fully ungrouped level. As for Affinity Designer, it does not even see that the image is grouped!
