Signing in with Google not working in Android OIDC auth, seems Chrome 80+ Cookie Policy

[satsangswami]

We are using FusionAuth™ version 1.17.0.

We are developing a Native Android & iOS App which will use FusionAuth as OIDC Idp.
I have implemented https://github.com/openid/AppAuth-Android and shall implement the iOS project from the same author.
Everything is working fine... Username/Email + Password login is working perfectly fine...However, when we use Google Sign-in (which is working perfectly on Desktop Chrome), but in Android when the app goes to fusionauth login screen.

1. It gives option for Google Signin
2. When clicked, It opens Google Signin Page
3. It perhaps, even signin to the google ( how i know, next time it doesn't asked me for password)
4. it closes the google signin window
5. I see the FusionAuth login form, it doesn't process anything and doesn't therefore return to the App.

PS: i tired lot for 2-3 days now to figure out, inspected the android chrome on desktop dev tools, it gave me this cookie warning, ( which i also get for desktop chrome but in desktop fusionauth processes, in android it doesn't). So i felt may be this is the issue.

Kindly let me know what can be done.

Sounds like a Chrome issue. https://chromereleases.googleblog.com/2020/02/chrome-for-android-update.html

Is there reason to think this is a bug with FusionAuth?

Sorry! for that, I didn't mean that, it may not be an Issue with FusionAuth, But...

1. I wasn't sure if it was An issue by Google or FusionAuth, and I can correct myself, if there was anything that We could do to solve this issue.
2. Well, if its an issue with Google, will it not be an issue for everyone else? How come nobody has reported this issue, making me feel that there is something I m doing correctly in implementing.

Please guide me on how to get pass this issue.

Thank you
