Hi,
I'm just confirming here that Push notifications are working on both Android and iOS.
We have tested it thoroughly and we can confirm that:
- Notifications are properly received in iOS 10 and iOS 11
- Notifications also work on Android 5, 6 and 7
If notifications are not working for you, please review the Troubleshooting section in this link:
