is Taraweeh an absolute obligation?

Re: is Taraweeh an absolute obligation?

I have heard from ulema that completing the Qur’an in Taraweeh as well as making 20 rakaat are both independent sunnahs. Now if what you’re saying here is true, then why is it an issue in the first place? According to this (considering the practice was not later changed), Taraweeh would be done at home individually anyway, so whether people are reciting 1,2,3,5 or whatever number of juz in the masjid wouldn’t make any difference. Allahu Alam
