Troubleshooting casting issues
I Don’t See a Casting Icon
Devices need to be compatible and active for an icon to appear on the workout video screen.
- Check Device Compatibility
- AirPlay Apple devices are compatible with Airplay
- Android devices are compatible with Chromecast
💡Tip: If your devices are not compatible, try a third-party app such as AirScreen or DoCast.
- Check that both devices are on the exact same network, not just the same router. If your router has a 2.4GHz and 5GHz band (e.g., 'HomeNetwork' and 'HomeNetwork_5G'), ensure both your phone/tablet and TV are connected to the same one. Avoid using a guest network, as these block devices from communicating with each other. You cannot cast via cellular data.
- Enable casting on your TV: In your TV's settings menu, look for AirPlay, Chromecast, Screencast, Mirroring options
- Ensure your software is up to date on your devices - phone, tablet, TV, Chromecast, Roku, Firestick, etc.
- Reset Connections
- Toggle Wi-Fi off/on
- Restart your TV/device
- Try a different browser
💡 Tip: Still not able to cast? Use a hard-wired HDMI cable from your device to your TV.
My video freezes or loses progress when I press pause while casting
In order to workaround the pause issue, try exiting full screen mode (X) and then pausing it in the player.
I was able to cast, and now it's not working
