Are others understanding it this way too: that sometime in January, I can opt-in to a Bilt 2.0 Cardless product, and after that but before February 6, I can close the WF Bilt card to not have it converted to an Autograph. And then I get a Bilt 2.0 card anyway?

I would prefer to not get a new auto-converted Autograph without the $500 new sign-up bonus WF is offering for Premier account holders. I am happy to give the Cardless products a shake (or at least see what they offer).
