As far as I understood and what worked for me is like this
1🌸 Enter the story (which has 3 or more chapters)
2🌸 Click the star in each chapter
3- write a comment of more than 10 words
4🌸 Do this in 3 chapters
5🌸 repeat the same thing in 3 stories
PS: If you don't receive anything, close the app and log back in 💜💜
I hope it helps you
