Update:
I got this email today:
Thank you for your patience in awaiting a decision. Currently, the waitlist is unchanged. We anticipate that we will know more as it gets closer to the April 15 deadline and we will keep you updated on the status of the waitlist. If seats become available, we will make offers of admission. If the admission committee needs additional information, we will contact you.We will provide you with a waitlist status update on April 7, 2021.
Not totally sure how they can give a status update on the 7th because I'm pretty sure that accepted people have until the 15th to decide...
