The new article about Mary Magdalene says:
The Catholic Church calls Mary . . . “the apostle of the apostles” because she was the first to bring news of Jesus’ resurrection to the apostles. . . . But this does not make her an apostle. And nowhere in the Scriptures is she called such.
Apostle is from the Greek word to "send forth", like a messenger. Just as Paul was "an apostle to the nations" because of being sent forth, but 'not one of the twelve'. On that note, Mary was told by Jesus to "go to my brothers" and tell them about his resurrection. But WT just can't bear to say that about a woman, just like they've always lied about Judge Deborah, calling her only a prophetess, and how they never looked into the alternate interpretation of Paul seemingly saying that women should keep silent in the congregation.
