Can anyone confirm this app is working? Emails to support to assist with installation would be great, for example, once installed, try to connect for setup but get popup that email is not found. Probably a step we are missing, but cannot reach anyone any ticket or phone for assistance. (Giving a 3 star out of hope and the app looks like it is what we need , if they reach back and all goes well, will return for more stars!)
