We are building a service that would handle push notification through APNS token authentication implementation. It is a multi-tenant service. We are aware of the fact that sharing same connection would cause TooManyProviderTokenUpdates (429) error. Therefore, we limit each connection pool to one app only. And we are only refreshing the token every 60 minutes. However, we are still running into this error lately. We are running multiple copies of our application simultaneous balance the load. Each one generates a different token. Is this a problem? Is sharing provider tokens across workers the only way to avoid this? Please advice.
