One YouTube user has spotted this new timer in the top right corner of the popup, with the individual later sharing the screenshot on Reddit. Another user in the comments reports seeing this popup as well, so it could appear to more customers in the days ahead. While the duration of this timer isn't revealed, we expect it to be somewhere around 30 to 60 seconds. The rest of the accompanying text within the box is unchanged from YouTube's initial experiment, with bullet points listing the benefits of subscribing to Premium, while the options to Allow YouTube Ads and Try YouTube Premium are also present.
