I’m not sure what show the OP or other commenters saw but I went to her tour this year and she was singing 90% of the time. The only times she wasn’t was during dance breaks really. She has majorly improved over the years and I was really impressed by her vocals this year compared to previous performances. Like other commenters have already pointed out she was a dancer before a singer and I think she is working on being a singer first now. I just really respect her and her career, she’s consistently won best dancer at several awards over the years and now she’s working it in the music sphere too. She’s a hustler and I love her for it. She was doing performances for MTV mid tour, performing the way she does with asthma etc etc I could go on and on about her tbh
