User of Firebase Auth here - got the same message and was similarly confused. Good to know I'm not the only one, but hope this gets resolved somehow. When Google was bragging about 30% of their code being AI-generated, the client ID gathering must've been part of that...

Also got this message for a client ID that's definitely being used in prod. Are you able to link the Reddit thread?

Google Cloud support is an actual joke. I have no idea how to navigate their chatbot and speak to an actual human. Awful.

We got and update from somebody at firebase on reddit and they confirmed it was marked incorrectly: https://www.reddit.com/r/Firebase/comments/1ky75x3/comment/m...

Now you can also see the warning for specific keys in the google cloud UI (and that one seems correct)

Same here.. 1 Production apps, sign-ins occurring frequently. They only freaked out every Dev in the world..

Same here. Received it for 3 production apps with regular traffic going through Oauth. No idea how to "use them" while they're already in use.

I got a corrected email today with less clients.
