I used this plugin for push notifications: cordova-plugin-fcm. It’s wel explained and documented how to use this plugin. And for iOS push notifications you’ll need certificates. On this page you will find the information on how to make these certificates. https://firebase.google.com/docs/cloud-messaging/ios/certs
Thank you! We ill test it and if solve I will return here. (For information: We found another problem with IOS the server need use IPV6 and IPV4 because the Apple Cloud return some responses and answers in IPV6 and it generate an error. Our node sdk for FCM is under IPV4 only. So on, maybe this is our problem.)
