By the way: I am not sure that is about Android version but my Android 9 device is working correctly, not working on Android 10
Notifications work for other cases (ex: when app is active or background)
The problem is: when app is waiting on background and phone is locked for 7-10 minutes, notification does not appear.
After unlocking the phone notification appear correctly
I thought the problem is phone is sleeping after a while, so used a foreground notification service library to keep phone awake and solved issue with this workaround. I hope this helps: https://www.npmjs.com/package/@supersami/rn-foreground-service
and there is a documentation for this package: https://javascript.plainenglish.io/react-native-foreground-service-f7fc8e617fba
Please comment if you have questions, I would like to help.
