Hi slayer36,

Thank you for sharing the tool link. However, I am currently facing an issue where my account gets blocked after downloading a single video using this tool. Could you please advise on a solution to resolve this problem?

Additionally, is there an option to download the entire course in one go, as my account gets suspended after the first download?

Thank you.

Seems like we cant do anything for now as it is the issue from Learnyst only. PFB SS from developer only.
