I have not, and spent a considerable time on it. Any of the payment emails that come in with the subject line “You’ve Got Paid!”… We just have to copy the content and send an a separate email back because the subject line is too cringey. I’ve talked to Wix support about it several times, and every time they seem to have less information on their forms / emails that go out than even I do. I suppose you could custom create an entire form and code what the subject line would pull from, I just don’t have that kind of skills or time to spend on it. Please update if you find a way though
