FWIW Andrews apparently gets a fair number of calls/complaints about the signature priority from what I could tell. Maybe if there's some sort of way to email someone who would be in a better position to fix it or at least make their marketing clearer.
BTW do we know if any other issuers besides WF and AmEx have decided to implement contactless on their physical EMV cards? Apple Pay goes pretty far but still has gaps (and AmEx cards supporting contactless either have a FTF or insanely high AFs).
