Amplify API GraphQL - Unable to change local API Key with the one generated online

Question

To update my API key, I used to go on AWS AppSync → Settings and generate a new one.

After that, inside my local app, find and replace my old API key with the new one... Until yesterday this worked fine but now, no matter what I do, when I run amplify status it outputs my old API key.

I also tried amplify update api with no luck. Later I tried amplify pull to see if it updates my local API key with the new one from the web app (AppSync) still no luck.

I already have a valid API key generated online, why I'm not able to update my local API key with the same key?
