For example, I created this post with this image hosted on lemmy.sdf.org as URL. The post never made it to ![email protected].
However, the same post with the same image hosted on pixelfed.sdf.org made it just fine.
This is just one example. I’ve made at least a dozen such posts and each time this happens without fail - unless the URL is something other than a lemmy.sdf.org-hosted image.
Not sure where to report this…
Send an email to [email protected] and they will help.
