I didn't receive any push notifications from apns on my iPhone

What I found during the development: The Apple phone has registered the device token and it is within the validity period, but it cannot receive the apns message. However, only after I re-registered the device token with this token could this iPhone receive apns push notifications normally... What's going on here? How can it be optimized?

There isn't much information in your statement.

  1. No OS version on your device
  2. No Xcode version you are using
