Hello. I'm Vlad, developer from unbiased.co.uk.
We've got a bit weird issue during updating of customer billing details on staging environment. It isn't changed after update. But on production everything works properly.
Could you please provide some details about this problem, because for now it blocks testing of huge part of our features on staging environment.
I believe my colleague Anand discussed with you regarding this issue and it's been resolved already. Please let us know in case you've more questions.
