Google api auth2 signOut not working
I tried as following and it worked. It is required to call auth2.disconnect() when the auth2.signOut() success.
<script type="text/javascript"> function signOut() { var auth2 = gapi.auth2.getAuthInstance(); auth2.signOut().then(function () { auth2.disconnect(); }); } function onLoad() { gapi.load('auth2', function() { gapi.auth2.init(); }); }</script><script src="https://apis.google.com/js/platform.js?onload=onLoad" async defer></script>
It can happen that the auth2 object is not loaded.( which would cause both issues presented in the question ).
This following snippet resolves that particular issue.
if(!gapi.auth2){ gapi.load('auth2', function() { gapi.auth2.init(); }); }
