There's no word on why the shows were canceled. But the tour's official Twitter page posted this message.

Prayers UP for @SZA

SZA's album Ctrl was a critical hit and did fairly well commercially.

But recording the album was full of conflict between SZA and her label TDE.

At one point, SZA threatened to quit, and the album only came out because TDE took her hard drive from her.

“They just took my hard drive from me,” the singer told The Guardian. “I just kept fucking everything up. I just kept moving shit around. I was choosing from 150, 200 songs, so I’m just like, who knows what’s good any more?” “Give me another month and it would have been something completely different,” she added.

SZA hasn't been on Twitter for three days.  Here is one of her last Tweets:

Anger depletes the body .

We'll see if her latest hiccup has anything to do with that, or if she's just sick or something.
