Google Play Games Services not able to login - returns Canceled

I'm using Corona SDK and trying to add Google Services to my game and followed the tutorial here but the sign-in fails. I've tried debugging with Android Studio and logcat and noticed that gpgsInitListener throws the following as soon as the login starts:

event.isError: {
      isError = true,
      name = "login",
      phase = "canceled"
    }

Funny thing is that I never have the opportunity to choose which account to use (I think other apps show which email is being used and ask to continue). After I access the scene containing the code, I see a "Google Play Games" popup and then a spinning wheel followed by a black screen.

My code is exactly the same as in the tutorial, except for the packageName, appID and leaderboardID. I've signed the app with Corona and then uploaded the APK to the Google console (so the SHA1 fingerprint should be correct). My app and game are published in the internal test status and I have added my email to the list of testers.

In the logcat I see the following messages:

And looking at the doc:

The attempt to sign in to the Games service failed. For example, this might happen if the network is flaky, or the user's account has been disabled, or consent could not be obtained.
