Citi has changed the bonus verbiage on the Citi Strata Premier card. Previously it stated:
Bonus ThankYou® Points are not available if you have received a new account bonus for a Citi Premier® or Citi Strata Premier℠ account in the past 48 months
Now it states:
Bonus ThankYou® Points are not available if you received a new account bonus for a Citi Premier® or Citi Strata Premier℠ account in the past 48 months or if you converted another Citi credit card account on which you earned a new account bonus in the last 48 months into a Citi Premier® or Citi Strata Premier℠ account
Only really an issue if you product change an existing card to the Citi Strata Premier.
