"Recipient time zone" based push notifications not working

[revolter]

I followed these steps:

a. cloned the Messaging example project
b. changed the bundle id to my own (that's already set to a Firebase console app)
c. ran the app on a real device and accepted the permissions request

I then created a couple of notifications similar to this one yesterday:

And I didn't receive any of them.

I successfully received "Single device" and "Send Now" push notifications.

Could you confirm that you did not uninstall the app after sending the notification. The scheduled notifications are scheduled locally and if the application is uninstalled the local notification would go with it.

[revolter]

So the data notifications are sent immediately to the existing devices, even if I schedule it to be sent the next week?

[revolter]

So, a new user that installs the app after a push notification is scheduled, will receive it or not?

[ianbarber]

The message is immediately sent to the device, but not displayed to the user until the scheduled time.

[kroikie]

@revolter correct, only users at the time of the scheduling will receive the notification.

[revolter]

@kroikie, but, if the users at the time of the scheduling don't open the app at all, will they receive it?

[kroikie]

Yes, once the users are able to receive "now" notifications then they will be able to receive scheduled ones.

[revolter]

But this documentation page states that:

On iOS, FCM stores the message and delivers it only when the app is in the foreground and has established a FCM connection.

[kroikie]

That is referring to data messages. Scheduled messages (as all messages from the console) are notification messages sent through APNs.

[revolter]

But doesn't that mean that the users will receive a notification immediately after we set it in the console, and then the scheduled local notification?

[kroikie]

Yes that is correct. The device will receive the notification (not displayed) and then a local notification would be scheduled.

[revolter]

How can you receive a notification which is not displayed? Resty from the support told me that "You can create a notification message and a notification + data message only, not data message alone".

[kroikie]

The message will be sent with the content_available field set to true, this will make a silent notification. Once received silently it is then scheduled.

[revolter]

Ooh, I see. Is the content_available field supported on iOS 7+?

[kroikie]

Yes.
