Hi all, I'm trying to send 1000 notification payload to APNS server for the same device token. When my program sent out the notification payload to APNS, through http/2 and getting the response 200 for all my requests. And it confirms that the payload is sent to APNS server. However, the device cannot receive any notification, did i missed anything!
Putting aside the question of what you were trying to accomplish (sending notifications in a batch like that would overwrite each other, and only the last one will be delivered - depending on how fast are you able to deliver the requests), sending that many notifications to the same device in quick succession will risk put you being put in a deny-list and you would not be able to send any more notifications until your server is cleared.
If you have already done this, and cannot even send single notifications, try a different server from a different IP address. If that works, then your first server is likely being blocked at this point. You would have to wait for a while without spam or DoS like activity for the deny state to reset.
