I'm really confused. What does the notebook say? Again, if all it says is "More in future updates. Stay tuned!", it means you've seen all the currently available content.
Under hints for Emily, interact and do chores and watch TV. For Olivia, interact and compliment her outfit. I feel like I've done every part of day for every location and don't know if there's more to do but haven't seen anything like 'stay tuned'. Last story thing for Emily was red dress and did that photoshoot and for Olivia it's killing the bugs.
Again those hints are actions to raise their stats, they do not progress the story. If you don't see the "Stay tuned" message there may be an issue. Could you DM me your save file on Discord? https://discord.com/invite/6k9aKFYkH3
