so? any progress?

@ErcinDedeoglu Facebook seems to not care much about releasing new Facebook Unity SDK. You can however build it yourself. This issue was fixed in more recent version of Facebook SDK, including the one that the github version of Facebook Unity SDK uses. Would be nice if they would actually bother to soon release update for the Facebook Unity SDK. Wouldn't get our hopes up

instead of justifying Russophobia and the genocide of Russian-speaking people, you better learn to work and finally release a fixed sdk!

I have a similar issue - lots of users crashing at login. 😬

Reproduced in-house

Unity Editor Version: 2021.3.9f1 Unity SDK Version: 14.1.0 Installation Platform & Verison: Android version 12 (Pixel 3 XL)

The exception happens when I try to log in with a Facebook account.

As @snorrsi mentioned above - the issues seem to be patched for a long time in Facebook SDK.

I saw that 29 days ago we have a PR to bump this to v 15.0.0

Still, it seems that the fixes lie in 15.1.0

Sadly to say, I gave up on with Facebook login. After a long time, I deleted it from my apps and lost thousands of users. I will never use it again.

Ran into the same problem now, as Google enforces API 31 compliance to push apps to the Play store. How could it be that such an issue is still open, after more than one year?! It is so easy to fix, just fixed it for my own Unity plugins within minutes.

Are there instructions on how to build the .aar files yourself? I would prefer to hotfix this for the SDK version I already have installed.

I now checked where the app crashes. It is in the facebook-core code. Is there a repo where I can find the source code for this?
