Error sending push

Hi,
I run my own blynk server 0.16.2 and have an iOS 9 as client. The Arduino nano issues a blynk.notify command but I never see the message on my iPhone. The iOS is logged on with roma@ahu.xapto.org. The notyfiy widget is present.

The blynk log states:
18:02:43.028 ERROR - Error sending push notification from hardware. For user roma@ahu.xapto.org. Error sending push. Problem : MismatchSenderId

Any properties file I’m missing? What is the SenderId?

Thanks

Hello. Push notifications for iOS not supported (because of Apple) on local server.

Would it work with an Android device?

Yes, it works with Androids.
