Please try these troubleshooting steps:
3. Go back to your scheduler and check that there is a black play symbol next to the name of the class (see BODYCOMBAT below) , which confirms that a Virtual class has been scheduled. In the image below, BODYPUMP is a live (instructor led) class and will not play content.
Lastly, remove the Apple adapter from the iPad and HDMI cable from the adapter and re-connect. Then try to play a class in admin mode by unlocking the padlock to the top right and navigating to the Classes tab, then select a release to play. If nothing plays there is a break in the connection with the screen which should be reported to your AV provider.
