Magento 2.3.6 - Customer Login is not working as it should

[jan-petter_hanv]

Hi Everyone, 

We are facing an issue with customer logins, is like they are partly logged in. 

When a customer logs in there is no logout button but a login button, create an account button, and Welcome message saying I'm logged in. 

Sometimes when the customer is going to the cart to pay they are told to sign in again but when sign in all their items disappear from the cart. 

All of the above happens on Incognito mode and all browsers.

We are using Porto Theme, can this be a Theme issue?

Hello @jan-petter_hanv ,

Do a quick check on magento 2.3.6 default, I am sharing link below :

http://139.162.47.20/magento236/

Which I got from : https://bsscommerce.com/blog/magento-2-demo-free-with-sample-data/

you can check if same behaviour is on core Magento, if not then you need to check with your theme provider.

Hope it helps !
