Hi,
It seems that "Default Payment Option" doesn't work in the payment tab of opc. I am using joomla 3.9.3, VM3.4.2 and OPC 2.0.370.081018. OPC Template is threecolumn_special_blue_css3 and I have tested on other temaplates also and it still does not default to the option I have chosen.
Is this something you are aware of, or is it a new bug?
Cheers
Martyn
