Been reading articles about the Shuri casting and man...there's a good amount of fake news out there in print.
Some gems I've read:
-Shuri hasn't appeared in the post-Secret Wars MU.
-Shuri challenged T'Challa to a fight for the BP mantle, and won.
-T'Challa trained Shuri in case something were to happen to him and a successor was needed (I've read this a lot for a while now, where has this happened? Haven't seen that explanation given in the comics).
So much for doing some research.
