We are currently looking into a Chromecast issue with the FB Plus ads free player. The error shows "A JWT is required, but was not provided" with code "VIDEO_CLOUD_ERR_TOKEN_REQUIRED". You san see another thread about this topic here: https://www.fitnessblender.com/community/discussion/17559/what-is-this-error-code
We'll keep you posted and try to resolve as quickly as possible!
Thank you for your patience, Brandon
