Taobao sub-account can't receive customer service news.

First, the team in Niu Qian checked that this sub-account is not online, so restart Niu Qian or restart the computer online. Is the weight set in sub-account management? If the weight is not set to 0, you will not receive this message. If the weight is set, you can download all other sub-accounts, including the main account, to see if you can still receive messages.
