I'm super thankful that there is now a preflight panel! It's already helped me catch a few errors. Question though (and it may be that I just don't know how to use it yet):
I have several yellow errors and a few red errors. I see how it shows me which object that is if I double click, but I'm not sure how to fix it (i.e. several images have the yellow "non-proportional scaling" error, and I don't know to fix it.)
Thank you!
