I can't sign in or simply use ChatGpt on Apple Intelligence
So I am physically in Mainland now, but my device is 16 Pro, both region and system language(as well as siri language) are set to En(US). I saw other local guys can use it, too. When I tried to sign in chatgpt, with google account or openAI account, I got a error said: "there was a problem signing in to your chatgpt account." When I tried to use chatgpt without an account, it still didn't work. I don't think it's the internet issue, for I didn't have any trouble signing in the ChatGPT APP and websites on both Safari and Chrome, seeming that the way to chatgpt THROUGH apple intelligence is not available.
Do any of you have the same problem or what?
