Is "in detail" a common combination to use? If so, could you give more examples?
Native speaker’s answer

Yes, "in detail" is an expression commonly used to mean "thoroughly," "comprehensively," or "closely." The speaker has used this sentence to indicate that the topic in question has been discussed closely or comprehensively already in the video series on sleep. Ex: Once you meet the manager, discuss the contract in detail. Ex: We didn't talk about our issues in detail, but things have mostly been smoothed over.
