For the best streaming experience, we recommend using the Chrome browser. If you’re already using Chrome, please clear your cache and history, then open a fresh browser window. You should also make sure you are using the latest version of Chrome. If the trouble persists, you can also try a different browser and see if that helps.
It should also help to manually adjust the video quality. Start playing the class and you'll see a gear icon in the bottom-right corner of the player. Click on the icon and the streaming options will appear. The lower the number, the lower the video quality—meaning the class will play more smoothly with a slow connection.
If you go through these steps and continue to have streaming issues, you may need to check your router and/or modem for any connection issues.
