I want to send notifications to specific users using tokens. firebase-admin can't send multiple tokens so I'm using:

for obj in queryset: token = obj.app_token message = messaging.Message(android=android_config, data=data, token=token) try: messaging.send(message=message, dry_run=False, app=default_app) except Exception as ex: print('Error %s' % ex) 

But it seems that "FCM" is blocked due to the fact that I send a lot of requests per second. Because after that I can not get a notification for a while.
Can this be solved?
