I've found out that the cause is that since Flask 2.3.0 SESSION_COOKIE_DOMAIN does not fall back to SERVER_NAME.
In previous Flask, if SESSION_COOKIE_DOMAIN was not set, then the cookie will be valid for all subdomains of SERVER_NAME.
Since in my application after authentication (in appdomain.com) the user is redirect to her homepage in her own subdomain (username.appdomain.com), then I had to set SESSION_COOKIE_DOMAIN so that the cookie would be valid for all subdomains of SERVER_NAME.
So I set this configuration:
SESSION_COOKIE_DOMAIN = ".appdomain.com"
and it's working.
