I have the following code to set subscriptions to a simplenews newsletter on or off:

    $user_load = User::load($userID_current);
    $newsletter_subscriptions = [
        'newsletter1' => 'on',
        'newsletter2' => 'off',
        'newsletter3' => 'off',
        'newsletter4' => 'off',
    ];

    foreach ($newsletter_subscriptions as $system_name => $value) {

        $subscription_manager = \Drupal::service('simplenews.subscription_manager');

        $newsletter = \Drupal::entityTypeManager()
            ->getStorage('simplenews_newsletter')
            ->loadByProperties(['system_name' => $system_name]);

        if ($value == 'on') {
            $subscription_manager->subscribe($user_load, $newsletter);
        } else {
            $subscription_manager->unsubscribe($user_load, $newsletter);
        }
    }

in the $newsletter i got back NULL even though the properties exists (checked by this:

$newsletter_storage = \Drupal::entityTypeManager()->getStorage('simplenews_newsletter');
$system_names = $newsletter_storage->getQuery()
    ->execute();
foreach ($system_names as $system_name) {
    \Drupal::logger('simplenews')->info('Simplenews system name: @system_name', ['@system_name' => $system_name]);
}

whats wrong with my $newsletter? Does someone have experiences with simplenews 3?

This code does not prove at all that the property `system_name` exists. The array values resulting from `$query->execute()` are always [arrays of entity IDs](https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Entity%21Query%21Null%21Query.php/function/Query%3A%3Aexecute).

It seems that chatGPT and Drupal are not best friends, so i had to find the solution the oldschool (long & painful) way. The solution was to provide the right subscribe() arguments, so i didn't need the $newsletter.

$user_load = User::load($userID_current);
$newsletter_subscriptions = [
    'newsletter1' => 'on',
    'newsletter2' => 'off',
    'newsletter3' => 'off',
    'newsletter4' => 'off',
];

foreach ($newsletter_subscriptions as $system_name => $value) {

    $subscription_manager = \Drupal::service('simplenews.subscription_manager');

    if ($value == 'on') {
        $subscription_manager->subscribe($user_load->getEmail(), $system_name);
    } else {
        $subscription_manager->unsubscribe($user_load->getEmail(), $system_name);
    }
}

There is no need to put the line initializing `$subscription_manager` inside `foreach()`. It is sufficient to initialize the variable once.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
