With the latest update I found the autoplay blocking feature and it causing me problems on YouTube (not allowing videos to autoplay). The YouTube help forum pointed me to the problem and a solution. Problem is even after having whitelisted YouTube autoplay still doesn't function correctly. The next video in the queue will now load, but I have to hit play for it to, well, play. The only solution has been to disable autoplay blocking entirely. Would be a great feature if it worked properly and consistently.
