(Update 1/28/21: Readers are reporting seeing these referral links and signup offers back again.)
A few readers reached out about the absence a referral link being available on the American Express Green card. All other Amex cards are eligible for one referral offer or another, including the business Green card, but the personal Green card stopped being able to generate a referral link as of around a week ago. You also won’t see a bonus offer FOR the Green card when using another referral link.
It’s unclear if this is a temporary thing or permanent, and one reader tells us that select cardholders can still refer, but it seems to be gone for most people.
