This is a common question on the web but I didn't found any solution for my problem...
I have the same warning message in console on all my rails apps when I click on a link to an other page
Edit: if I comment "turbolinks.start() on application.js, the warning doesn't appears !
Just need to find THE solution now...
The resource http://localhost:3000/assets/application-eda55435df3b9385974c23342a8ac80ac010272673a829df638338aed54fe933.css was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it has an appropriate
asvalue and it is preloaded intentionally.
I have no tag in my application.html.erb but I use Turbolinks if it can help you
Application.html.erb
<head>
<title>Parto20</title>
<meta name="viewport" content="width=device-width,initial-scale=1">
<%= csrf_meta_tags %>
<%= csp_meta_tag %>
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
<%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload', defer: true %>
</head>
application.js
import Rails from "@rails/ujs"
import Turbolinks from "turbolinks"
import * as ActiveStorage from "@rails/activestorage"
import "channels"
Rails.start()
Turbolinks.start()
ActiveStorage.start()
