Add custom cron interval

Hello,

Your custom cron interval code is overriding other codes. Please update it as demonstrated below:
Old code:
public static function wpim_cron_schedules() {

return [ ‘weekly’ => [ ‘interval’ => 604800, ‘display’ => ‘Once Weekly’ ] ];

}

Updated code:
public static function wpim_cron_schedules( $schedules ) {

$schedules[‘weekly’] = array(

‘interval’ => 604800,

‘display’ => ‘Once Weekly’,

);

return $schedules;

}
