I checked the exam information on the ZhiPu app for the past two days, but I couldn't retrieve the exam time and location in Guangzhou. This could mean that the exam hasn't started yet or that there's a problem with the app (but I saw that other cities had exam information). Also, how do I test the transmission function after receiving a new device? I just listened to the 8:00 PM Yuexi Jinsha sign-in event, and I was wondering if I could transmit after registering.🤓☝
