There's an intended cooldown on this interaction, it's not supposed to always be available. If it's literally never available that'd be a problem, though. 🙂
@JenChelChi So it hasn't reappeared even after reloading the lot/save or restarting the game?
I'm having the same issue. I don't believe it is due to a cooldown because I was in the same lot for at least one full in game day and Post Updates interaction didn't reappear. If I leave the lot and reload it comes back as well. This doesn't have a time limit; I can use the interaction, leave immediately then go back to the lot and I'll have the interaction available, even if only about 20 in game minutes pass. Additionally, I can do the interaction on other lots such as the movie studio but again in these lots I can only do the interaction once. Another thing I've noticed is if I queue two different "Post Updates" interactions then my sim will complete the first interaction and then stand confused waving their arms with a question mark thought bubble above their head.
If it is just a cooldown thing and I need to wait longer, I think it would be clearer if it showed up greyed out with a message saying something like "No more comments to reply to for now" or something. However, it doesn't make sense from a gameplay standpoint that doing one of the three interactions would stop you from being able to do the remaining two. I understand that the replying to comments interaction causes a decent boost in followers and fame and it makes sense to limit this interaction, but limiting the other two doesn't make sense. My expectation as a player would be that I'd be able to complete all three interactions before they're all unavailable.
Hope this provides some extra info to the people who need to see it!
