In a Magento 2.0.7 with very little customization when we disable a country in State is Required for
in Stores -> Configuration -> General -> State Options
the state field in the checkout process shows up as non required field for this country. However, when we try to proceed without selecting a state this is not possible and we get the error message
Please select an option.
below this field. If we select a state we can proceed.
This kind of feels like a bug, maybe it's just a rogue javascript validator? How can we make the state field in the checkout truly optional? And do we face a individual problem or a common bug here?
Also worth mentioning, the Allow to Choose State if It is Optional for Country
option has no noticeable effect for us.
