Although YouTube was popular with most schools as there are additional accessibility options including translation, it was also proving problematic with some that block student access to YouTube. Even sharing specific URLs to whitelist wasn't enough!
Therefore, to make the videos available to a larger number of schools we have taken the decision to move the hosting of the Time2Code videos from YouTube to Tella.
If Tella is still blocked by your school, you should be able to whitelist https://www.tella.tv
Subtitles are still available but there is no translation option with Tella at the moment.
