Firebase Remote Config Fetch failed with user not authorized

Question

I'm trying to set up my production application to use remote config, but I'm getting a FirebaseRemoteConfigFetchException. This project is already deployed, we use FCM, Crashlytics and Dynamic Links. If I use the dev project on firebase everything work just fine. So I don't think it's the google-service.json configuration. The only difference between the configurations is in the production instance I have the SHA certificate fingerprint setup.

Answer 1

After digging a little bit, and looking all over the place, I found that for some reason I had to go to https://console.developers.google.com -> Enable API and Services -> Firebase Remote Config, and enable that API. After doing that everything started to work again.

I hope this helps someone in the future, cheers!
