Apple Watch Fitness displaying old apple id email

Hello! So last year I changed the email address associated with my apple id. I updated it on all my devices, my contact card etc, however since I updated it, my mother and I can't properly compete/share activity on apple watch fitness. Our wins against each other are different for us both and sometimes it won't update our activity at all. Whenever I send her an invite to compete it shows my old apple id email and not my name or new apple id email. We both deleted and re added each other as contacts on our phones and updated the email address associated with my contact card, reset out apple watches and iphones etc. but Nothing seems to work. I know my apple watch is connected with my new apple id, it shows up as such in every space on my phone/watch, except when I send my mother competition or activity sharing invites. Its the weirdest thing, does anyone have any suggestions?
