Just to follow-up on #104 : Downgrading to pytube==9.5.6 though solved some issues but it created more complex ones related to changes only pytube==9.6.0 addresses.

@SuperKogito what issues are you referring to?

I am not sure if my reporting can be accurate on this, since I made some changes on the code to avoid using the Words API but here is the ull trace-back related to pytube:
