No Support…

If you bought ‘More Visibility Rules’ this is my fix for RCP :

From file : …/plugins/if-menu/src/conditions-multiple-options.php
Snippet of code fixed for conditions-multiple-options.php :

// Third-party plugin integration - Restrict Content Pro
if (in_array('restrict-content-pro/restrict-content-pro.php', $activePlugins)) {
    $conditions[] = array(
        'id'        =>  'restrict-content-pro-active',
        'name'      =>  __('Any RCP membership active', 'if-menu'),
        'condition' =>  'rcp_user_has_active_membership',
        'group'     =>  __('User', 'if-menu')
    );

    $levelsOptions = array();
    $levels = rcp_get_membership_levels();

    if ($levels) {
        foreach ($levels as $level) {
            $levelsOptions[$level->get_id()] = $level->get_name() . ' - Level ' . $level->get_access_level();
        }
    }

    $conditions[] = array(
        'id'        =>  'restrict-content-pro',
        'type'      =>  'multiple',
        'name'      =>  __('Has Restrict Membership', 'if-menu'),
        'condition' =>  function($item, $selectedLevels = array()) {
            $userId = get_current_user_id();

            if (!$userId) {
                return false;
            }

            //RCP methods library : https://help.solidwp.com/hc/en-us/articles/360053121033-rcp-get-customer-by-user-id

            $customer = rcp_get_customer_by_user_id($userId);
            $customerid = $customer->get_id();

            $level_ids = rcp_get_customer_membership_level_ids($customerid);

            $access = false;
            //$selectedLevels = membership levels ids for the current menu item
            foreach ($selectedLevels as $selectedLevel) {
                $access = $access || in_array($selectedLevel, $level_ids); //Show menu if at least one membership level allowed 
            }

            return $access;
        },
        'options'   =>  $levelsOptions,
        'group'     =>  __('User', 'if-menu')
    );

    $conditions[] = array(
        'id'        =>  'restrict-content-pro-expired',
        'name'      =>  __('Expired Restrict Membership', 'if-menu'),
        'condition' =>  'rcp_user_has_expired_membership',
        'group'     =>  __('User', 'if-menu')
    );
}

Maybe can do better but it works for me… 🙂
