It happen to me first time (I worked on few RStudio servers).
I set

There is a line in ~/.config/rstudio/rstudio-prefs.json:
"show_user_home_page": "always",
But after login there is new session created or I am connected to one. It never connect me to existing opened projects.
Is there some other option to change? Conflicts maybe?
As I mention it is first time I see this, on other servers everything is ok.
