I understand. It was just a lot more of a 'to do' than expected. Aside from the opt in document changing, the system capabilities on each affected product, automated notices, frontline training, account opening, marketing, customer understanding, etc. all had to be changed.
It is easy to recommend improvements, and walk away. It is another thing to work through them issue by issue. It just isn't a battle I'd side with again, especially if overdraft income didn't show us to be an outlier from peers.
Good luck in whatever you end up doing! I agree the overall overdraft opt in on the A9 isn't ideal, I believe we went that route to avoid additional documents requiring signature/uploading/scanning and so on.
