Notification arrives in iphone5, but not in ipad about grocer HOT 4 CLOSED

After removing the app from iphone and then installing again it, it also doesn't work.

@llvc If I recall correctly, you'll get a new device_token for each install. Did you go through the whole registration flow for each device, and keep the tokens for each install (across each device)? We've seen problems in the past where folks tried using old device_tokens or tokens from different environments (e.g., sandbox vs prod) and messages fail to send.

sure, I update the each new device token and try to send a notification with it. But also fails.

I have compiled the ios project and generated pem file by following urls.
