Perplexity Frustration! Time and time, Perplexity simply drops my question. It really is a huge impediment to using the service, which is a shame, because it does have some minor plus points. It's definitely an interesting idea, but until they can get the user interface up to other search engine and AI standards, it's just another "Ask Jeeves" of the future. Since its launch, I have seen no discernible improvement.
