Musk's Grok is truly amazing. I bought a safe, but my iPhone 17 just couldn't connect to it. It kept failing via Bluetooth; it would fail every time I turned it on. I contacted customer service, and they spent over two hours trying, granting all permissions, but it still didn't work. Then I contacted Grok, and initially, she guided me through setting up Bluetooth, but I did that too, and it still didn't work. She told me to log into my account on another non-Apple phone, connect successfully, and then log into the safe's mini-program on my Apple phone. Then I could see the devices I had linked. I finally succeeded! Asking Doubao (a Chinese Q&A website) was exhausting, but I still couldn't get an answer. Furthermore, I discovered that Doubao's math skills are particularly poor. I asked her how many hours it takes for Comex gold futures to open from Saturday's closure to Monday's opening, and she told me about 25 hours, from 6 AM Saturday to 6 AM Monday. Can anyone tell me how long that is? Isn't it about 48 hours? I'm still a bit confused. @grok, how long is the interval between the closure of Comex gold futures on Saturday and the opening on Monday?
