Remove the language selection on subscriptions block form

I also have this problem, I could not find anything in the options.
preporcess solved the problem:

function YOURTHEMENAME_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id) {
  if ($form_id == 'YOURSIMPLENEWSFORMID') {
     $form['langcode']['#access'] = FALSE;;
  }
}

I just hide it through css by now.

Thanks for the report. There is another issue ✨ Allow configurable form display for subscriber langcode Postponed however it is postponed on a Drupal Core fix.

Is this a new problem for 4.x?

Automatically closed - issue fixed for 2 weeks with no activity.

How can an anonymous user choose their subscription language after this change?
Now I need to use the suggestion from #2 ( https://www.drupal.org/project/simplenews/issues/3385578#comment-15222697 🐛 Remove the language selection on subscriptions block form Fixed ) but the other way around, forcing it to TRUE.
