Hi, I suggest for the next release to have the feature to browse through the checkout steps, so that way user can modify shipping address, billing address ot credit card info.
I'm currently trying to find the way that the user can correct then credit card info after an error, like when "The security code is incorrect".
I noticed also that when gateway returns the error message, the Shipping/Billing Address info is lost, but I couldn't find where is the session being cleared.
If anybody knows thanks!
