Dear Eva,
Thanks for your information, I have to apology to you, my last answer let you confuse to my question.
Actually, it’s not the problem of “GA account could not show any record by user sessions”, but is Google Analytics could not get any feedback from my web site, please see this picture.

I’m quite impressive of your hard working for these “session math theory of Google”, but how to let my GA code working from my site is the most important task. Is there not any client of you with that problem?
Please do help me to check it, please..
