Specific methods:
1. First, we need to check our network status. If the network connection is not good, we will not receive the message.
If it is mass news, it may be because we are no longer in this group.
3. You can also check whether the sending object is correct. If the sending object is incorrect, of course, the message will not be received.
4. If the above three questions are not checked, there may be something wrong with the nail server. At this time, we can only wait for the official to repair it.
5, you can also call the nail customer service phone for consultation.
