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?
I didn't receive any push notifications from apns on my iPhone
There isn't much information in your statement.
- No OS version on your device
