I have a Chase Sapphire Preferred®. Activated: 11/16/2019.

I would like a Chase freedom unlimited.Is it possible to downgrade to this card?

I called Chase. They said I must wait 1 year before downgrading, however I can apply for a Chase freedom unlimited if I dont want to wait.

Is this true? Must I wait 12 months before downgrading, or is there an option to escalate / downgrade sooner then 1 year? Should I just apply for the freedom and cancel the Sapphire Preferred?

My other cards are:
Chase Biz Prefered ink: activated 9/10/2019
Chase Amazon.com card: Activated 3/1/2019
