We have large number of users for a game and we have written our own PHP server for sending push tokens. Now when we send push from server then server sends Push to all devices and shows no error. But over device, push is not received.
We tried to send to single device from the server with same application certificate then it worked fine. But when we send it to all devices then push was not recieved. Is there any limit imposed by Apple on number of push in 1 second OR is there any other suggestion which we can follow to send push to large number of devices in parallel?
