Detailed Problem Description

Seems after Facebook migrate to Facebook login for Business they change the rule to authorise to soc accounts. In my olde project version I am using next technologies:

• Capacitor 6
• Firebase 10.13.0
• @capacitor-firebase/authentication 6.1.0 (which allows me to login to Facebook accounts)
  Everything works fine and login method redirects me into Facebook app (on my device), let me login and return back info that I requested.
  After Android introduced their updates related to API 35, it requires Capacitor 7. In this case I have to update my project with next technologies:
• Capacitor 7
• Firebase 11.0.0 (at least)
• @capacitor-firebase/authentication 7.2.0
  With all of this updates Facebook login does not work and I see a message that "This app is not available"

I added all required Facebook permissions but seems nothing help.
In on of articles I saw that for web implementation should be used "config_id" key with value. And here is the question - does Firebase support this key, and can I send it to Facebook to login in my app?

Steps and code to reproduce issue

Demo with deferent environments:
With Capacitor 6, @capacitor-firebase/authentication: 6.1.0, firebase: 10.13.0

With Capacitor 7, @capacitor-firebase/authentication: 7.2.0, firebase: 11.0.0
https://github.com/VashAlex/Capacitor7-login-to-facebook

Steps to run projects:

1. run "npm i" in each project
2. fill in information about Facebook App and Firebase app
3. add GoogleService-Info.plist file into IOS directory
4. run rpojects on ios simulator or real devices

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @VashAlex,

I believe your question is related to the backend configuration and integration of Facebook developer accounts with Firebase Auth, is that correct? If so, then I think your best route to receive an answer to your question is by creating a new ticket with Firebase Support. They handle backend questions where this issue forum is more for SDK issues.

If your question is about SDK configuration then please let me know. Thanks!

I think it is more about SDK, about functionality in the SDK. Can SDK send an additional param to Facebook so I can login with my Facebook account. If yes - so this question is not for SKD
