Incorrect. Dw's account that has business and personal was recently upgraded to new site
They will probably eventually upgrade everyone to new site, but currently, the easiest sure way to get the new site is to make a new login only for personal accounts (there is no need to touch current one) by simply calling chase asking for another login only for personal
keep us updated if u get the bonus
just completed spending on the CSP from last round of preapprovals in my account and got bonus no issue
