I want to change my login credentials in UiPath Academy but I can't. Please help

My current work email account (xx@cvx) is both my primary email and user name(xx@cvx) in UiPath Academy. I changed my primary email to a gmail (yy@gmail). Still, when I am trying to login it’s not taking my new email rather it’s accepting the earlier one (xx@cvx).

My work email is soon going to be deactivated and after that I won’t be able to do anything with this email account. Please help.
