Of course! If you want to watch your courses on your TV screen, you can do it using Chromecast, it's very simple. First of all, make sure you are using your Wi-Fi connection, as the synchronization will not work if you are using your data.
When you enter the video of your course, click on the Chromecast icon that appears at the top right, next to the three dots icon.
Once there, just select the Chromecast you want to stream your course to and that's it! You can start enjoying your lessons on your TV screen.
In case the icon does not appear, despite having it activated, we recommend you go to the Google Home app and make sure that, from there, the Chromecast is detected. If so, you should have no problem activating it from the Domestika app.
