[This is a issue know to the team, Moshe told me about it, but I want to make it transparent (and linkable) to the whole community, that's why I post it here].
Symptom: You post a blog comment, but it's not visible to others - you see it with a "Your comment is awaiting moderation."
This happens when: your comments contains any links.
Workaround: re-post it without links.
Or (better!) : approve it in https://blogs.sap.com/wp-admin/edit-comments.php
(Thanks Jelena for providing this approval link! )
PS: just came to my mind: this might be a feature in the original intention, as you don't want spammers comments (with links in them) to immediately go to public...
It doesn’t work out here, though, as it punishes the users that take the extra steps to provide links to the stuff they talk about
