Bear 2 didn’t come with SVG support at the moment. Do you mind sending me one of those SVGs which causes this problem? I’d like to understand what’s happening here.
Seconding this as a feature request. The most disturbing things is that a placeholder does not get displayed. Maybe say at least that the image could not be rendered.
I’d also like to have this feature considered to be implemented. At the moment I’m pretty frustrated with the image quality PNG images are exported to PDF. So I was expecting to be able to use SVG just to discover it is not supported.
