Answer 2

You have an issue at Private content fetch.

The private content like customer data cart, wishlist, customer data is specific to individual users, it’s reasonable to handle it on the client.

Use our customer-data JS library to store private data in local storage and show at your browser.

See how Magento2 implement Private content

So, it means when you have logout then private content taking time to update.

Also check the Request Url is cache from the server End.

Please check this two factory and you get a clue about the issue from this.
