It's also not working using with firebase-BOM.

Solution

Here is the guidance, our api key on Google Cloud credentials is not working for firebase installations from starting.

https://github.com/firebase/firebase-android-sdk/blob/master/firebase-installations/API_KEY_RESTRICTIONS.md

Now, in https://console.cloud.google.com/apis/api/firebaseinstallations.googleapis.com/metrics metrics we are getting 200 and in app messaging is also working fine.

So, if you are facing "Firebase Installations Service is unavailable" error then update the google_services.json file by making new credentials on google cloud OR restrict the firebase installations in the current key you are using for android.

Thank You.
