Hmmm, not sure, @Jonniey1, good question. Keep in mind that transactions completed through the shipping feature have real human eyes on them, researching and manually verifying each transaction. That's a pretty specific question on something that I don't believe we've had to experience yet, so I'm not sure how to answer.
Honestly, I can't give a specific timeline because I'm just not sure @Jonniey1 - sorry about that.
BUT, what I can do is get your case escalated. It looks like you reached out to the Payments team already, so I'll let them know you're waiting on the next steps. They should be reaching out via email and responding to your case shortly
