A change of dance partner affects several lists
For the opening dance, the partner list serves as a working document: it assigns names to a meeting point, a formation or an order of appearance. So a cancellation affects more than just you. If a replacement shows up while the people in charge are still working with the original name, the handover before the entrance can stall. A private confirmation does not replace the official change to the partner list.
Also keep dance participation, admission and accompanying guests separate. A replacement for the opening dance does not automatically take over a seat or a ticket. Your original prom date does not have to change either. The different roles of a prom date and a dance partner remain the same even after a cancellation.
For your message, just include the relevant organizational details: the original person can no longer take part, and you would like to change the dance pairing. A diagnosis, personal conflicts or screenshots of the cancellation do not belong in the year group chat. If you also have a joint course booking, changes to it are handled separately from the prom list; signing up for the prom dance course is a separate process. This makes it clear to the committee which message concerns the opening dance. Use a single message thread for the partner change, so the confirmation, deadline and approval stay together instead of getting lost among private chats.
