@Fifweg Yes, I noticed it as well. There was definitely something amiss. I hope she's feeling well. It was about 8:50 am, so not a normal time to depart a 2-hr show.
Jayne had to quickly "pivot" (the term Jayne used later during her Denim & Co. show with Gary) and start hosting earlier than expected.
Note that QVC's Program Guide online now says the show was Accessorize Your Spring, Stacey Rusch and Jayne Brown.
But before Stacey had to leave, the Program Guide stated
Accessorize Your Spring, Stacey Rusch (no mention of Jayne Brown co-hosting).
I always check the Program Guide every morning to see if I'm watching or not.
