Is Gemini's Notebook feature really buggy..?

I've recently started using the Notebook feature to keep convos related to a project i'm working on in one place. But I find they can be really buggy. I'll have a very basic, short conversation, and then I'll get an error: *Something went wrong (1152).* The Pro model will technically work, but that takes a lot longer when trying to have a simple conversation.

Is this a me issue, or is it just really buggy?
