Thank you, sandjohnson, for the reports!
About Gracie not skating her new SP, I'm not really surprized. I think she would've already announced the music before she skated to it.
And from Ice Network article month or two ago:
So I think(while we don't know the reason) she's purposely not saying anything about her new SP."We're keeping the short program under wraps a little longer," she said.
Whatever the reason, she skates the FS in a few hours. Best of luck to her!
