Android - Firebase invites returns error - Resultcode 0 - Emails sent SMS not sent

Question

In my nativescript-angular app, I am using the nativescript-plugin-firebase to implement firebase invites. I have setup both the SHA 1 and SHA 256 in the firebase console I have used the boilerplate code shared in READ.ME to test the invites (see below).

firebase.invites.sendInvitation({
  title: "Invite title here",
  message: "Invite message here"
}).then(
    function (result) { // SendInvitationResult
      console.log(result.count + "invitations sent, ID's: " + JSON.stringify(result.invitationIds));
    },
    function (error) {
      console.log("sendInvitation error: " + error);
    }
);

I find that while on IOS the send invite function works as expected. On android I face 2 issues:

1. Email invitation is sent to the invitee but an error Resultcode: 0 is returned and I do not get back the invitation ID

2. SMS invite is not sent to the invitee.

A similar issue has been reported here - but there are no suggestions on what can be done to fix the error. Would appreciate any suggestions.

Regarding to this thread there seems to be a bug in Firebase's Invitations for Android Oreo and newer devices.

Update: Starting January 24th 2019 Firebase Invites is deprecated.
