The Scrolling Gallery and View Counter auto-upgrades should all be completed by June 2017. You will see a Confirmation Auctiva Account Message which will be shown on the Auctiva Acct Dashboard once the upgrades have completed for your account. If you haven't received the confirmation message its because many of the auto-upgrades are still being processed.
Again by June 2017 all upgrades should be complete. But if you aren't already aware please note, come June 2017, even if an eBay listing still contains a piece of active content, the listing will still be live and purchasable on eBay, the only thing that will change is that piece of the item description that contains active content will not render.
If the old version of the Auctiva Scrolling Gallery is the only thing you need to update, you can contact our Customer Support Team and they'll be able to run a command that will update Scrolling Gallery in your listings.
