The writer's assistant did not receive the verification code.

Collection times exceeded, and mobile phone security software intercepted it.

1, the number of acquisitions exceeds the limit. Because the writer's assistant can only get the verification code three times a day, if the number of times that day has exceeded, he can't get the verification code and needs to try again the next day.

2, mobile phone security software interception. Because the mobile phone security software intercepted the SMS verification code, the writer's assistant could not receive the verification code, so it was necessary to turn on the mobile phone security software, temporarily turn off the interception function and try to obtain the verification code again.
