1: Can a device token be registered to a topic more than once time?
2: Will duplicate pushes be sent if we have a device token registered to more than one topic and we try to send the push to both the topics? Example:
I have topic A and Topic B and device D is registered to topic A and topic B now if I send the push to both the topics then will the push be sent twice to the device? If yes then how can I avoid this as we dont want to send duplicate pushes to the user.

3) Can we send pushes to different topics in one go?( I mean where we pass the topic arn can we pass different topics comma separated?
