I personally believe why a few shows will not be on disney plus at all..
this shows rights are currently getting confused by audiences, one side believes its owned by disney, the other side believes that its owned by the authors of the w.i.t.c.h comics, the authors own the comics, they might not own the tv show. so they had a lawsuit, i couldnt find who won tho.

Even tho Customer Support said its coming soon, nothing has been said officially and it might be a hoax, again im not sure if the rights are given to disney or abc.
Even tho it was on Netflix in Latin America, not many people (from the general disney public) knows about this show, so disney doesnt really care to put on in the first place.
