{
    "message": "",
    "igAction": "news",
    "actionPath": "news",
    "collapseKey": "reachability_silent_push",
    "pushId": "5e84b4a725e4bHb53015e40H5e84b9408611dH141",
    "pushCategory": "reachability_silent_push",
    "intendedRecipientUserId": "48637238848",
    "badgeCount": {
        "direct": 6
    }
}

this is the last thing I get from the push event

I think its an Instagram problem or Instagram is changing something in their MQTT.

how can I monitor the MQTT data?
I found an Instagram patch with the latest version in this repo
I tried to reverse engineer the com.instagram.android:mqtt with Frida script that was provided in repo but its doesn't work and I'm not experienced in reverse engineering I hope the project owner helps us to update this repo

I tried to reverse engineer the com.instagram.android:mqtt with Frida script that was provided in repo but its doesn't work and I'm not experienced in reverse engineering

The script is probably outdated:

instagram_mqtt/frida/mqttListen.js

Lines 10 to 24 in 0f80649

	/**
	* search for the string 'MessageEncoder'
	*
	* EXPECTED:
	* any.any("MessageEncoder", new IllegalArgumentException(() + "Unknown message type: " + a), "send/unexpected; type=%s", b)
	*
	* OR
	*
	* search for the string 'No message encoder'
	*
	* EXPECTED:
	* throw new IOException("No message encoder");
	*
	* CURRENT: v123.0.0.21.114 @ x86
	*/

I haven't really kept up with any changes to MQTT on instagram.

Yeah, i can't get realtime notification too

Actually same here! I used to use this library regularly months ago but I think problems started to occur. Sometimes some notifications were coming else some were not. I can't see any realtime notifications today (using last version of instagram_mqtt library). I believe though I've made the correct settings even though the past months have been working regularly, the most frequently used pending chat notification has stopped coming. I checked the logs saved so far and just noticed it today.
