Hello Friends I have developed application to test Push Notification service provided by apple. I got the device token after registration and also on the server side which is configured on windows using C#.net platform, certificate is installed and there is no issue too. I have send 2 notifications from server to apple server but still havent got any alert on device. What is the reason behind that? After how much max time should I wait to get notification alert? Or am I going wrong any where? Please help. Thanks in advance.
