This is an issue which i experience very often. I used to use Inkscape and want to migrate my SVG files to Affinity Designer.
My experience is that AD completley ignores the ry property of rounded rectancles.
I attached a sample svg files which includes two rectangles. One where only rx is set and one where only ry is set. Affinity Designer does not import this correctly.
I hope a fix will be included in the next release as this bug is preventing me from a complete migration to Affinity Designer.
Edit: This post describes the same issue as the original one, sorry for the duplicate comment.
