Hi, when we move mockups to another project or page, all comments that were attached to a mockup stay on the old page/project. So it means they do not follow what they are belonging with. It is a redundant issue that I meet when I try to curate my designs and I would be happy if you could fix that. It should work with a cut/paste or copy/paste.
I have seen some posts were you explain that we need to use the right-hand button but it is clearly not intuitive as I have never seen this after more than 1 year of use of your software now.
