I'm in charge of multiple Drupal 8 website and with some of them, the hidden field form_token is non-existent when I'm using the website anonymously.
Everything works fine when I'm logged in.
I'm sure everything was working before the quarantine but I didn't check before updating to 8.8.6
I tried deleting the custom twig templates of the webform and I checked my theme.theme
webform version is 8.x-5.13 for some and 8.x-5.16 for others.
