I'm having trouble casting the Full Body Fit workouts to my television. I don't recognize the casting button you've referenced in the lecture.
Depending on which phone or device you're using, the Casting instructions may be slightly different than what's described in the lecture.
The cast button we reference (labelled J) is just one example of how this may appear on your device but is specific to iPhone - this is the iOS Airplay button. If you don't have an Apple TV but use an iPhone, check out this article for information on how to cast.
If you don't use Apple devices, here's a simple article that goes through a few options for casting from the Android system. You may need to scroll to find the best instructions for you based on which devices or apps you have available.
If your casting issues are not answered in the above articles, we recommend doing a quick Google search for "Casting to [DEVICE 1] from [DEVICE 2]", where Device 1 is the location you wish to view the video (ex. "Chromecast", "Roku TV"), and Device 2 is where you're currently viewing from (ex. "Samsung Galaxy S9", "iPad Pro").
