Unable to change email address & Display name

Hi, I’m trying to change my e-mail address on the Nvidia website but I keep getting an error stating “Email cannot be changed at this time”. Does anyone know if this is a temporary limitation, and if so, how it can be lifted from my account? Also i am wanting to change my Display name if possible,

Kind regards, J.M.S

Is this the main account email on the Developer Program account? The email can not be changed in the Forum account Profile. If the change does not work, you should wait for 24 hours before trying again. If not, please use the support contact.
