Has anyone solved this issue yet? For several months I thought the problem had finally cleared up as we weren't getting the duplicates any more. But starting in either November or December we have started experiencing the issue of transactions only appearing once (or not at all) in Tessitura, but processing twice through our credit card processor. I know many people were experiencing this as well, but never saw if anyone found out what was going on?
I'm following this conversation because we've just switched to Windcave (earlier this week) and I believe I am seeing two sets of duplicate transactions on yesterday's reports. Hoping to gain some understanding of the underlying issue.
