The And-But-Therefore template is useful precisely because it temporarily puts aside the need to craft public-facing language, and focuses instead on the key structure of the narrative you need to communicate to your audiences.
I totally agree that And-But-Therefore is an efficient way because it can attract the readers' attention and can also efficiently introduce how we can help users to solve their worries also it makes readers more willing to continue to spend their time exploring the next steps. I changed my perspective because at first, I didn't notice the importance of And-But-Therefore and I didn't know the sequence to tell the story clearly, so sometimes the story makes the readers confused and don't understand what the key point is and now I understand that what kind of narrative is suitable for providing to users. In addition, I consider that the And-But-Therefore is a good way to let users know if the solutions are useful and suitable for helping them resolve their worries through a clear narrative.
