3 years ago Do these devices have GMS installed? If not that may be the problem. I do not have one of those devices so I can't test for you.
https://github.com/react-native-device-info/react-native-device-info#hasGms
Messaging requires Google Play Services (aka "GMS")

3 years ago Thanks @mikehardy, I will try to check if GMS existed there in the user devices first.

3 years ago Got reports from users and confirmed that all firebase/cloud-messaging functions will not work if GMS not exist. Will need to find another way to send notifications to Huawei users. Thanks @mikehardy for helping.

3 years ago I'm not sure what the plans are for supporting HMS devices from firestore but it is sorely needed It appears OneSignal can handle push notifications for both

2 months ago We are currently observing crashes on Huawei devices. Does this library supports notifications on Huawei devices?
Issue
Recently I have transferred my app's notifications service from AppCenter to Firebase Cloud Messaging. iOS and mostly Android devices are working fine. However, I have just got some reports from users that their app will hang in a blank white screen when opening the app, they are mostly using Android devices - Huawei p40 Pro.
I think the issue is mostly happened in below codes, as this is the only feature I have added between versions. Inside my app's login screen:
I believe it is mostly because Huawei got banned from Google Play service, but I have no idea how to solve it. This is a non-fatal error which will not crash the app, so I cannot trace it from any crashlytics. Does anyone face the same issue? How can you solve it so the app can run normally in new Huawei device? Please kindly help, thanks.
