Hello Alan
At the point of setting up the chart of account itself the currency would have to be changed before going to the banking page and connecting the bank.
Can you go to accounting and chart of accounts and check if the currency set against that account is GBP?
If you then go to new as if you were setting up a new bank account you should see where it has currency there is a drop down to change the currency you set up an account. Do you get that option?
Kind regards
Emma
