Why don't flash messages always work?

Question

Laravel

Let's say we have this code:

return redirect()->route('home')->with('notification',  "Бла бла бла");

In the view, the output is:

@if(session('notification'))
    <div class="notification">
        {!! session('notification') !!}
    </div>
@endif

The same request, on the home PC the message is displayed every other time! (loading the page takes about a second)
Sometimes they are not displayed on the working PC! (page loading is almost instantaneous)

Because of what messages may not be displayed ??

Answer 1

1) The problem occurs only when using the Google Chrome browser
2) Namely, the wrong path to the site icon.
The correct path to the icon solves the problem.
