I'm using OneSignal for mobile push notification, but some devices' ids got in invalid_player_ids when sending the notification from my REST API.
It have happened with different devices. Both android and ios.
Current i'm using an android device. And my scenarios is: I install my app on android. The id is generated and sent to my backend application. My application try to send notification to the generated id, it fail with error invalid_player_ids and my device id.
How i can manage to solve the id to check if its valid or not?
Thanks
