[iOS, US] Payment Fails

Issue:

Payment to UK contacts seems available, but fails.

Details to reproduce:

Select US Monzo account from the top of the payments tab.

Select Pay

Choose a saved contact in UK, Monzo to Monzo or external.

Both Payment types will fail. If the account is Monzo to Monzo it will ask for the amount in USD. Any account saved with account number and sort code will ask for GBP.

I realise this is unsupported functionality, but I should not get this far. Contacts on the main payments tab show up blank which prevents this error.
