Referring for BA Amex via Avios.com or the Avios app

[craiguk58]

I’ve just had an email through from BAC advertising that I can refer for a BA Amex via the Avios app or Avios.com. Is this new? They are offering referral points plus the enhanced 50k bonus on the BAPP compared to referring via Amex and only receiving 33k.
I’ve looked on the Avios app and the option is there but it’s not giving me a referral link. I can’t find the option on Avios.com

Reading the email again it sounds like it is getting confused with referring via Amex as it’s mentioning Amex T&C’s on making a referral.
Very confusing.

I received this email also. I am unable to find the referral link via Avios.com. Anyone know how to find it?
