When I tried to tag this question What is the difference between two URL in Facebook Ad Manager?, I found that there is no tag about facebook-ads-manager or similar tags. This raised a suspicion that this type of question is off-topic here, because I suppose Facebook advertising is as important as Google advertising for marketers. So if it's on-topic, someone should have asked it before I guess.
According to What topics can I ask about here?, apparently internet marketing is on-topic here. I wonder this includes social media marketing as well?
The answer for the question Can I open a question about Social Media? says "If the question is related to social media management and strategy for your own website, then it would be fine here." I understand that it's a yes. I'm not sure that it's correct or not.
