FCM Device Group

[Nitin Agarwal]

Hi,

I have been exploring a method to send messages in batch and came across the concept of Device Groups.

https://firebase.google.com/docs/cloud-messaging/android/device-group

Since there are CRUD operations available on a Device group, my assumption is that it is reusable. Is there any expiry on a device group?

Also, what is the limit to the number of device groups we can create.

With Regards,
Nitin
