I wonder if the adverts in the "personal super-assistant", per the blog post, ("that helps you do almost anything"!) will have the same triggers as the shopping assistant, which pops up underneath messages right now in the web UI.
When first trying 5.2, on a "Pro" plan, I was - and still am - able to trigger the shopping assistant via keyword-matching, even if the conversation context, or the prompt itself, is wildly inappropriate (suicide, racism, etc).
Keyword-matching seems a strange ad strategy for a (non-profit) company selling QKV. It's all very confusing!
Hopefully, for fans of personal super-assistants--and advertising--worldwide, this will improve now that ads have been formalised.
