Hi @CLOUDFIRE91,

This seems rather unusual, but I'd like to get more context about what's happening here. Version 11.0.0 of the SDK has been released. Could you confirm if the issue persists with this version?

I don't know if you tried this out, but can you try if going to Assets > External Dependency Manager > Android Resolver > Force Resolve makes any difference? Could you list down the solutions that you've tried so far?

Thanks Paulinon for your reply. I have tried this Assets > External Dependency Manager > Android Resolver > Force
/Delete Resolved Libraries and all the methods. Nothing works . I have tick the custom main manifest to proguard file.
Nothing works.

May be i will try firebase 11. and i will update soon.

@paulinon i have open fresh quick start unity master for auth. and i have downloaded the firebase 11 sdk and i installed. There are lot of errors displayed . I have attach with it. Is there any Update for quick start unity master.

Hi @CLOUDFIRE91,

Thanks for the update. It turns out that Version 11.0.0 deprecated some methods which are possibly in the quickstart. I'll let the team know about this.

For now, could you try reverting to Version 10.7.0 and reimporting the SDK? Additionally, has clicking Force Resolve made any difference in your implementation?

HI paulion

I have tried reverting to version 10.7.0 and reimported the SDK. But the same error happens. Error is same. I have tried this stack overflow forum .
https://stackoverflow.com/questions/52518378/more-than-one-file-was-found-with-os-independent-path-meta-inf-proguard-android

it is also not working. and also i tried many forums in stack overflow. But no luck .
Coud you please some Idea how to solve it..

Is there any Update for quick start unity master.

I've just now updated the Auth quickstart to be compatible with the 11.0.0 Auth Unity SDK update:
firebase/quickstart-unity#1331

But that seems like an aside from your issue about the error mentioning coroutines.pro.
