@manton I believe I found the reason why some Mastodon replies are not shown as comments in blogs: I seems that these are unlisted comments, which do not show up on any timeline, just below the toots. Is there anything you can do about that?
Ah, glad you figured that out. We purposefully do not show unlisted comments on blogs or in the timeline. Mastodon users expect that those comments are somewhat private and so they usually don’t want them accidentally shown anywhere else.
Thanks for that clarification.
