Same for me. Cardio Acute is in process and the ER positions and the Med-Surg one are closed. All of the other units I applied to are in process. I applied on the day everything opened.
I haven't applied before, so I was thinking maybe their AI didn't like something in my resume/cover letter. HireVue says that it can take up to 48 hours to get a link so I'm holding out hope.
