"Join" extension won't function in Brave

Several users have brought to my attention that apps like "Join" won't work in Brave with #1380.
Devices cannot communicate and device the extension is installed on remains "unrecognized". Diagnostics in the extension show the following errors:

Steps to Reproduce

1. Install Join extension
2. Try to use the extension
3. When it doesn't work, run diagnostics

Actual result:

Extension doesn't function

Expected result:

Extension should work and device should be recognized.

Reproduces how often:

Easily/always

This is still an issue with the latest version of the browser (0.60.47 Chromium: 72.0.3626.119 (Official Build) (64-bit)). Anything I can do to help get this resolved faster? Basically, the only thing preventing me from switching fully to Brave.

FWIW - When I started collecting errors on the extension it failed on line 1963 with the following error: Error: File doesn't exist on your google drive: storedpushes=:=undefined.

In addition, when you run through the GCM Internals the connection state comes up as false.

I haven't spent a lot of time on this issue, but in my case it acts like it's not integrated with Google Drive even though I went through the setup. I've only been able to reproduce this issue in Brave. Going through setup in Chrome and Canary still works.

Hey, if it helps:
If you go to Join's chrome extension store page, in the "Support" tab, the user Sean Blonien posted 2 days ago (so Apr. 27 2019):

So it looks like the problem is related to regId?

+1 I rely on this extension quite a bit.

It's working perfectly now in Brave Dev Version 0.72.110 Chromium: 78.0.3904.70 after enabling Use Google Services for Push Messaging (Added in v0.72.73 - #2301 / brave/brave-core#3390 / brave/brave-core@cd3df93) . This finally enables Brave to work with Firebase Cloud Messaging, after GCM having been deprecated earlier this year (more info: GCM/FCM FAQ).
Note: This feature isn't available yet in Release/Beta channels.

There appears to be a bug though, where clicking the Relaunch button after toggling it on, untoggles the setting before relaunching. I got around this by toggling it on, and then running chrome://restart in a new tab. I've created #6633 for the bug.

• Step 1: Use Google Services for Push Messaging
• Step 2: ‽‽‽‽‽
• Step 3: Profit!!! 🤑💸

Can confirm, Join works great in Brave now. You just need to enable Google Services for Push Messaging as @LesterCovax showed. I'm on the Release channel, so it looks like this feature has made its way there.

Join has a self-test function under the diagnostics tab. All the tests pass in Brave 🎉

Tested on Version 1.1.23 Chromium: 79.0.3945.88 (Official Build) (64-bit).
