In the UK, the list of counties provided by Civicrm (and by the ISO) is mysterious to say the least to most UK dwellers. Many people think they live in a county which changed to something else years ago!
So, afaik it's best not to use counties in addresses with drop-down options - such as billing fields.
Therefore, how can one disable state/county in a billing address block? Or at least make it not required?
We use Authorize.net for most UK transactions.
Thanks for your help!

PS - I see this: https://issues.civicrm.org/jira/browse/CRM-19688 But I don't think it helps in this situation?
