Did you manage to solve this? If so, how? I'm having the same issue with expo-notifications. The expo notification tool and endpoint (https://api.expo.dev/v2/push/send) return 200 but on the dashboard (https://expo.dev/accounts/[org]/projects/[project]/push-notifications) every notification is marked as failure and there is no log where i can check what is wrong with my config (I followed the official docs though)
