I have an ionic app on capacitor both for android and ios. Everything works great on my testing environment using Firebase-Cloud-Messaging. I am able to send and receive segment notifications to both devices. The only concern I have is when I try to send a single device notification through FCM interface (send test message) to IOS. The device is not receiving it. I have tried many things already. And since it not working there in interface, it is also not working when i test it though CURL. On the other hand, android is working perfectly. Any suggestions?
