Reporting a bug fix Thanks for this awesome app. However at first when I installed it and enabled it  it dint work out (though I got a notification saying that night mode toggle has been inserted in my notification bar). This issue is faced by many users. A simple solution to it is just turn off your adaptive brightness settings and then turn night mode on. It will work perfectly. And once it works for the first time  you can again switch on your adaptive brightness and no need to do anything from thereon
