The player may have reduced quality due to poor network connection. You can resolve this by closing all other tabs, then re-open the browser from your link. Make sure you are using Chrome as your browser.
Auto Quality is a new feature where you can use the drop down to select ‘low’, ‘medium’ or ‘high’ to override the automatic quality setting and manually adjust the quality.
If you aren’t getting as smooth a watching experience, please select ‘low’ which should help.
If you’re still experiencing issues, restart your internet router or contact your internet provider.
