The message received is not stable enough
JPush iOS is a supplement to the push of the original official APNs, and it is encapsulated to help developers use APNs more easily.
Because the APNs themselves do not promise to guarantee the arrival of messages, the connectivity between the client network and the server side has a great influence on whether the APNs could receive the message in a timely manner.
