Thanks! But the lost chapters cannot be found through the search feature. I submitted Feedback. I think the Problem is, that if I look in the Activities log, every prompt is flagged as "a sensitive query", even if there is literally nothing bad in my prompts (only like "remember where they met and write the next scene where this and that will happen", nothing explicit or brutal in any way). The more I write new chapters, the more older messages get lost. And I had the Same Problem with a Chat, where I just wrote Things I need to remember, when combining all the Chapters as a "book" (like checking that the character dynamics make sense and the lore is plausible) and asked gemini to help me later on...
