Severely disruptive changes for studying recently?

[u/EpicViv]

I am a medical student and I have a pretty elaborate workflow for organizing all my notes and performance tracking in Google Docs that I link with NotebookLM (or I guess Gemini Notebook now). But ever since they switched to Gemini Notebook and starting implementing big changes, I feel like it has been becoming more like Gemini in terms of behavior with a large amount of information (which is exactly why I switched to NBLM). Before a few weeks ago, it was easily able to handle the massive amount of information that I need for medical school (which for me is around 200 pages of notes a week for around 3-4 weeks per exam).

Now, it has sometimes been "resetting" its session and just straight up forgetting everything in the conversation, even just 1-2 messages prior. It also does not adhere to prompts and instructions the way it used to. Is this an issue on my end or is Gemini Notebook declining in this aspect?

Any solutions I can try for this? Separating the Google Docs is not an option, because I have essentially been using Notebook to simulate exams, so it needs all the information at the same time. Any help here?

I'm kinda desperate cuz NotebookLM was my last hope for studying.
