Quota exceeded. Cross origin redirect sign-in is no longer supported in many browsers.

Project Settings

Hi, I need help with this. Yesterday, my website went down, and in my Firebase dashboard, I got this message: "Cross-origin redirect sign-in is no longer supported in many browsers. Update your app to ensure your users can continue to sign in."

The link sent me to Best practices for using signInWithRedirect on browsers that block third-party storage access on Firebase's website. But to be honest, I’m not sure what this means or how to implement it in my app.

This issue is preventing my users from signing in.

What have you tried so far?

Even Firestore disappeared, along with all the data. This problem happened to me a few months ago, and I solved it by deleting the mailto:[email protected] and adding it again, but this time it didn’t work. However, today the app is allowing users to sign in, but only on one device.

Apparently, it's working fine now, but I don’t want these kinds of problems to keep happening. How can I optimize the platform?

I don't have any screenshots because it's working normally at the moment, and all the FlutterFlow options seem good. Everything appears normal, except that you can only sign in on one device.

Did you check FlutterFlow's Documentation for this topic?
Yes
