One other thing that seems to be a problem now (and I'm sorry that IDK which ticket deals with A LOT of the AI breakage and rebuild that happened with the most recent Assistant upgrade) is that I have to create a Lens to point to assistant-specific URLs and turn on THAT Lens as a part of Web Search IN LIEU OF the old behavior which was to have the URLs be in the Custom Asst. prompt directly and turn off ALL web search (because the prompt had the search details already embedded in it).
I accept this behavior BUT it's annoying and feels like a regression where I have to do THREE things (PDFs in a bucket, custom assistant prompt, Lens) instead of TWO thing in the past (PDFs in a bucket, custom assistant prompt)
