I had an offer on my Gold card on online banking to upgrade to Platinum for 20k points even though I evidently don't meet any two year criterion. However I wanted to ensure I was approved for the much more valuable Platinum cashback before I took this offer. However, once I activated my Platinum cashback the offer disappeared from my account. Will Amex approve me if I apply for a normal Platinum whilst already having the cashback version? And does anyone have any experience whether it's worth waiting to see if the 20k promo comes back or just best to write it off?
