@kalpeshhiran, GitHub is intended for bug reports, please use Magento Stack Exchange for questions on how particular customization can be implemented.

Note that welcome message is displayed using https://devdocs.magento.com/guides/v2.2/extension-dev-guide/cache/page-caching/private-content.html, so, after login corresponding section needs to be invalidated.

[kalpeshhiran]

@orlangur I assume this is a bug and I am not asking for any customization.

When someone login to Magento 2.2.6 either with login form or login function provided by Magento setCustomerAsLoggedIn, behaviour should be same.

I am looking to see just default msg which is shown after user login (includes fullname), and not really looking to customize anything.

I will appreciate if anyone can help with that.

@kalpeshhiran no, please check the documentation I referenced. I suppose in the latter case private data section is not invalidated properly thus you see old data.
