There's nothing wrong with the code you've posted in the StackOverflow question. Can you share a full project that I can compile and run?

@yramanchuk @drishi94 do you have any updates on this?

FirebaseUI provides sign-in and auto-upgrade of anonymous users. It does not provide any UI or facilities for linking together two non-anonymous users. The error you're getting is because the provider...

The document you linked should say `Anonymous account linking` instead of `Account linking`. ~~You can use FirebaseUI to obtain an `AuthDataResult` that you can use to link to another provider~~....

You're right. We could probably add this to FirebaseUI reusing the existing UI and just returning an AuthDataResult, but for the meantime you'll have to use Auth directly.

I'll take a look at exposing an AuthDataResult callback.

This is not currently possible. `FUIIndexArray` and friends are entirely separate from `FUIArray` to the point where they don't even share a common superclass, and this is intentional--though their use...

Yep, sounds about right. Thanks for taking this on!

Is this the case for only FirebaseUI, or for Firebase Auth in general? It sounds like it may be an upstream Auth issue. @renkelvin @Yue-Wang-Google

I see what you mean, this is intended behavior by both auth and FirebaseUI, though we haven't thought about changing it to match Android in this case yet. You're right...
