I made an appointment for the fourth subject with priority, and the online reservation showed success. I haven't received the text message since the exam on the 9th. Can I take the exam?

Sometimes I miss texting. Since the appointment is successful, let's go. I've met it, too. At that time, I took the second exam, which showed that the appointment was successful. However, some people who practice driving together have received text messages and some have not. Then everyone took the exam. I was even more surprised. I didn't send a text message at that time, but I received it the next year.
