Data point: was expecting a rejection on the QF Ultimate but was approved.
Application submitted lunch time today - was required to input salary, expenses, mortgage payments, other card limits etc. Post submission received two emails, the 2-5 day email and the request to provide payslips at the same time. The application screen also reverted to the document upload screen after submission. An SMS was received a few seconds before the email came through. The SMS advised to check my email for the information request. I submitted the payslips straight after and was approved an hour ago.
No AMEX held for over 4 years, though was auto declined for this same card in December 2023 (probably as the previous AMEX I held onto was for only a month).
