I've had header bidding configured and operating properly on my site for several months. I have confirmed that Sovrn is getting the opportunity to bid on placements, and from the analytics page on meridian, I can see that Sovrn is seeing the requests.
However, Sovrn has never actually won an auction or delivered an impression on my site. I have sent a number of emails through standard support channels but this issue has never been resolved, or even explained to me.
Has anybody else had this experience?
