browser-sync does not refresh page after changes with Gulp

Question

I'm new to Gulp and I wanted to make use of its automatic scss compiling and browser sync. But I can't get it to work.

I stripped everything down to leave only the contents of the example on the Browsersync website:

http://www.browsersync.io/docs/gulp/#gulp-sass-css

var gulp        = require('gulp');
var browserSync = require('browser-sync').create();
var sass        = require('gulp-sass');

// Static Server + watching scss/html files
gulp.task('serve', ['sass'], function() {

    browserSync.init({
        server: "./app"
    });

    gulp.watch("app/scss/*.scss", ['sass']);
    gulp.watch("app/*.html").on('change', browserSync.reload);
});

// Compile sass into CSS & auto-inject into browsers
gulp.task('sass', function() {
    return gulp.src("app/scss/*.scss")
        .pipe(sass())
        .pipe(gulp.dest("app/css"))
        .pipe(browserSync.stream());
});

gulp.task('default', ['serve']);

I can call gulp serve. The site is showing and I get a message from Browsersync. When I modify the HTML, the page is reloaded. When however I modify the scss, I can see this:

[BS] 1 file changed (test.css)
[15:59:13] Finished 'sass' after 18 ms

but I have to reload manually. What am I missing?

I also faced a similar problem when I was new to browser-sync usage, the command-line was saying "reloading browsers" but the browser was not refreshed at all, the problem was I had not included body tag in my HTML page where the browser-sync can inject script for its functionality, make sure your HTML page has body tag.
