I am trying to download either Jabber Guest Access app or Chrome extension, but both of the links provided take me to dead zones on the Chrome and Play stores. It seems it might not be available to me. Can anyone confirm if this app is still active and available? Is it only available outside the USA or in Australia? Is there a direct link for downloading either that is not "https://chrome.google.com/webstore/detail/jbglbakaieakcdiaiabbihafndhapfki"?
