This is also happening to us, but on iOS only. We are using v8.0 of the SDK. The SDK seems to keep passing us between Facebook App and the WebView. Uninstalling the Facebook app allows us to successfully login.

Is your app have AppsFlyer? Your case reminds me #519

johnny-tictoc commented 3 years ago

@legoritma Yes, we are using Appsflyer. I'll try out the fix in that link. Thanks!

Hi, Thanks for the share. I tried AppsFlyerShouldSwizzle solution. Now, I have that line in the Xcode; image

But, the problem still continues. It does not solve it.

When I searched the term, I end up with the result in the image. I also double-checked Swizzling condition by logging it in the initialization with the code below and it is logged as "true". My problem looks like not related to the AppDelegateListener. Am I missing something? 

        id swizzleFlag = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"AppsFlyerShouldSwizzle"];
        BOOL shouldSwizzle = swizzleFlag ? [swizzleFlag boolValue] : NO;

        NSLog(@"Swizzle: %s", shouldSwizzle ? "true" : "false");

        if(!shouldSwizzle){
            UnityRegisterAppDelegateListener(self);
        }

From the logs you provided it looks like the issue is with Firebase. Facebook's deep link url get routed to Firebase's listener instead of Facebook's:
