Hello @Davin_WEI,
thank you for your message!
YouTube section
Sorting only works with videos that are already in our YouTube library, not with all videos available on https://www.youtube.com/.
Our library is updated from time to time, so you may see content that was released 15–20 days ago.
If you want to practice with any YouTube video that is not yet in our library, you can do so using our official browser extension:
Podcasts section
We are currently experiencing an issue with the Podcasts section, so content is unavailable in that section. We are actively working to fix this, and it will be available again with full content in the near future.
This behavior is the same for all languages (English, Japanese, French, etc.).
Thank you for your understanding, and please let us know if you have any other questions.
