If you're like me and have a Chromecast device, use Chrome as your browser and load our News page, then you may have experienced something very strange this morning – like all the embedded YouTube videos playing simultaneously.
After a lengthy search, I finally figured out what the culprit was. It seems that the Chromecast extension for Chrome (Google Cast) is now causing all embedded YouTube videos to play automatically. The issue is relatively new and we're hoping it gets resolved very soon. In the meantime, you may want to disable the Google Cast extension in Chrome.
Please note that the issue isn't just with our site – it's on all sites with embedded YouTube videos. A Google Cast update seems to have created the issue. [Sean]
