What are some restrictions that Google has to prevents a push notification from being shown to the user that we should know about?

Question

I tried sending 80K pushes at once, and Google either

Automatically revokes the push token or queues up the push and doesn’t display it to the user

i'm using FCM

80K.. Those are rookie numbers, you gotta pump those numbers up. — axwr, Jul 23 '17 at 21:14

There isn't any official documentation that states any mind of restrictions for the push notifications from FCM, other than the Message Payload size limit, the DeviceMessageRateExceeded error (kinda similar to Throttling, which AFAIK is no longer applied) possibly only for iOS, and TopicsMessageRateExceeded error to avoid spamming when sending to topics.

Other possibilities for a message not showing up could be because of the device(s) itself (see my answer here).
