Just a quick update, I received my auto-withdrawal this morning, so if people are still struggling to withdraw due to confirmation emails not coming through - you could try just to opt for auto-withdrawal.
You don't have to go for auto withdrawal, if you want to make a withdrawal to your profile address and you don't receive authorization emails.
Note that you don't need to confirm your withdrawal via email if you want to make a withdrawal to your profile address. So, withdrawal to your profile address should work even if you use slow or instant options.
