For the sake of completeness, I am updating this thread with a relevant excerpt from today’s blog post:
Magstripe ATM withdrawal support
In the UK, almost all ATMs use chip and PIN to validate your identity when you try to withdraw money. However, that’s not always the case elsewhere around the globe and in many countries, ATMs use the magnetic stripe on the back of your card to dispense cash. Up to now, we’ve disabled magstripe ATM withdrawals to protect against the increased fraud risk that these ATMs bring but from today, it is now possible to temporarily turn on magstripe ATM withdrawals for 24 hours. You can access the setting from your Profile or from a transaction that’s been declined by a magstripe ATM.
