Hey!
We automatically block ATM withdrawals outside of the UK when customers are not ID verified.
It might be your case - quickest way to get around this, send a message through the support chat. If your account is not ID verified, you’ll be sent an invite to go through a very quick and smooth in-app ID verification process.
It takes a minute to complete, then it needs to be manually reviewed. We are usually able to review these in real time 
If the declines are due to something else, we’ll be able to advise.
