To add to this I am able to replicate:
Preconditions:
Magento Version CE 2.1.1
PHP version 7.0.7
Full Page Caching Enabled
Chrome Version 53.0.2785.143 m

Steps to reproduce with Actual and Expected Result
When Full Page Caching is enabled this always results $customerId as null, disabling full page caching means the customerId is correctly returned.

$customerId = $this->_customerSession->getId();
            /**
             * Check the user is logged in
             */
            if (!$customerId) {
                return "User not logged in";
            }

This appears to only happen in Google Chrome. Firefox works as expected.

I have also this issue. I try to add some custome values in CustomSession, but when I do a getCustomValue, I have nothing.
If I disable Fulle page, it's OK.
Have you an explanation please ?

Thank you.

Same here.

Setting a session using \Magento\Framework\Session\Generic on a custom Controller returns NULL on the Block when cache is enabled. With cache disabled it works fine.

IT'S NOT A ISSUE! SEE HERE #3294 (comment)

I am having the same problem in Magento 2.2.1 as well .. I tried following code in a .phtml file...

$om = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $om->get('Magento\Customer\Model\Session');
echo $customerSession->isLoggedIn();

it did not return anything when Page Cache is ON, and when OFF I can see a value (1) printed.

What about this: https://magento.stackexchange.com/a/167112/62952

If you have a custom template just put: cacheable="false" in ypur block declaration in layout: example:

<block class="Custom\Theme\Block\Customheader" name="custom_header" as="custom_header" template="Magento_Theme::html/customheader.phtml" before="-" cacheable="false" />

You can try by creating an object of objectManager and should not use objectManager directly.

Use something like,

class Example extends \Magento\Framework\View\Element\Template
{
    private $_objectManager;
    public function __construct(
        \Magento\Framework\ObjectManagerInterface $objectmanager
    ){
        $this->_objectManager = $objectmanager;
    }

    public function getExample()
    {
        $customerSession = $this->_objectManager->create("Magento\Customer\Model\Session");
        if ($customerSession->isLoggedIn()) {
            $customerData = $customerSession->getCustomer()->getData();
            /*Your logic*/
        }
    }
}

I have already added cacheable="false" but it is not working in my custom block.
I have to clear cache then it is working.
