Cons of sending content-available=true and content-priority=high in BULK FCM messages?
While sending FCMs, I've noticed these two headers are important(message won't go without these headers), but what could be the cons of sending both of these headers as it is? I tried to read about these content-negotiation headers but could not find any information about them in internet. The internet says that we need these headers only in iOS messages, but instead I required these for android messages notifications. And are these headers location dependent? i.e only required if the location of transmitter and receiver is long? GCM/FCM=Google Cloud Messaging/Firebase Cloud Messaging.
