Hello, I sent push notification in broadcast to everyone.
I have almost 900K token and some of them said me that they didn’t receive the notification. Is there a way to see how much notification I sent?
Thanks.
Have you tried to inspect your Push Status collection inside mongodb?
Davi’s suggestion to look at your Push Status collection is a good start for investigation.
In addition, with such a large amount of tokens different considerations apply for you than for someone who is processing only a few hundred tokens. There are mechanisms like rate limits on a total amount of request basis, but also on a per device basis.
What you want to do is:
- (a) Make sure you clean out invalid tokens. Parse Server does a pretty good job identifying invalid Google FCM tokens, but not so much for Apple APNS tokens - which depends on the service provider. So you may have do get creative and look for other ways to identify them.
- (b) Send in batches over a longer period of time.
- (c) Mix the token order up to minimize the risk that you try to send many push notifications to the same device. After you send a large amount of pushes to invalid tokens of a device (because the user uninstalled the app, then reinstalled it), then even valid tokens will be rejected for a while as a temporary restriction.
These are just some of the - rather opaque - rules of push service providers that can throttle you and can cause users not to receive push notifications.

Tanks guys.
I checked the token and I do not have duplicate one (only few).
So I have to send about 900K notification.
On firebase results only 270K notification sent that day.
So maybe there was a problem on PARSE server (I didn’t’ found anything on logs)
The solution as you suggest is to schedule a JOB but I don’t know how 
I saw in the console that there is the possibility to schedule a “Cloud Jobs”
I’ll check on docs.
Thank you.
