Been working on this the past 2 days and Antigravity is driving me a little crazy. Can anyone give me some guidance on how to solve this. I am using React and Supabase. Works for web but having trouble on my Android build.
I understand, Error 10 on Google sign‑in from Android almost always means a configuration mismatch in your Google Cloud / Play Console setup, not a bug in your app code.
So basically, I see this after I click on Google to sign in to the app, click onto my email address, then a pop up shows up with Error 10.
Below is a checklist of attempts, I have tried with my IDE to solve the issue.

| 7. Device Cleanup | DONE |

Double / Triple check on Supabase and Google Cloud for URL Config, Auth and Credentials. Everything checks out fine, uploaded screenshots to my IDE to check as well.
At the moment, I’m waiting for it to propagate which takes about 6 hours time. I’ve done this 3 times already. I read that this is a bit of a common issue, so I am hoping someone here may know what is going on and can help. Feel like I am stuck in a loop now.
Thanks in advance.
