I often find Siri irritating when asking questions about certain things, or ask her to look up stuff on the web. Surprisingly I looked at the ChatGPT settings and down on the list is one option with Siri: “Confirm ChatGPT Requests” This is on by default and I have now turned it off. I now find that Siri acts and responds far better with ChatGPT this way. I hope this helps others with their iPhones and would be interested to know you found this helpful or not.
