I am using FCM for notification and its works fine ... But one of my clients is addressing the issue multiple times that his device (iPhone 7) sometimes received remote notifications whenever the app becomes active...
I checked the logs from the server the notification was sent on time and everything is working fine from the backend...
Is there any possibility that causes the delay in the notification ... on low power mode notifications don't work and when the device is out of network can cause a delay in this issue ... but this is not the case because he receives notification when the app becomes active...
