Im experiencing an issue with Magento 2.1.7
I want to login users programmatically by only their email.
But after setCustomerAsLoggedIn it still shows sign in or create an account in the header.
If I flush the cache it shows the correct data.
This issue is the same as https://magento.stackexchange.com/questions/171087/show-customer-name-after-setcustomerasloggedin
/* Magento\Customer\Model\Customer $this->customer */
$Customer = $this->customer->loadByEmail('firstname.lastname@example.org');
/* Magento\Customer\Model\Session $this->customerSession */
Thanks in advance!
