Today I woke up to an email from Iberia to reset password for the IB+ assigned by Chase. I also saw the Avios posted and another email said profile up to date. I was unable to reset the pw with that link but I was able to go to the app send myself another reset pw and got a new email that worked. I am able to see my account from app but when I try to login from chrome or edge says IB+ And pw combo not correct. To make an avios booking the app takes u to safari web page and asks u to login again so that is not working either.
I used the strategy above now to contact IB - I think maybe since chase used the same email I had perviously used to create an IB account maybe it’s blocking something on their end? Will keep everyone posted
good luck to all!
