As far as I can tell they haven’t officially announced it, but there is a new update to the nominative roster, in which Canada have changed their initial registration, bringing Spence in in place of national all around champion Rose Woo.
Also on this update is a change for Japan, whose national AA champion Kasahara Arisa also appears to be out, with her and Woo joining Konnor McClain and Sarah Voss on the sidelines it’s not proving to be a good year to be a national champion. Kasahara is replaced in the six woman Japanese team by Ashikawa Urara.
