Anybody know when it will be available at Unity Package Manager?

The individual packages seem to be live for me

If you are referring to the Google scoped registry for the package manager then I have some bad news for you..!

I'm just happy google is trying to address an issue that's hard to even reproduce. We are talking about less than 0.5% of sessions after all.

You might want to wait before updating if you're using RemoteConfig, there's a breaking issue on initialization in a build: https://github.com/firebase/firebase-unity-sdk/issues/751
