I got a message from a Dell helper (BP-CSTE), whoever that is who suggested "This seems to be a network issue. please change the network connectivity and try to update the email address". I couldn't see how it was a network error as I could readily change my password yet I couldn't change my email address ! Anyway, the only change I could make was to switch from ethernet connection to wi-fi but as I was still connected to my home modem/router I didn't see how that would "change the network connectivity" but it still didn't allow me to change my email address. So I tried opening the Dell website in a new private window of Firefox and surprisingly it worked the first time I tried it. So I have to say that I was very disappointed with the "Dell" response as it seemed that they weren't really interested in solving it but I fixed it myself anyway.
I want to change my email address on my Dell Account but when I try to change it I get an error message (see screenshot) saying "We are sorry but there seems to be a problem. Please try again after some time." [IMAGE] I eventually give up as it keeps showing this message which is such a pointless message as it doe not give you any idea of what the problem is. Does anyone have any suggestions on how I can get this changed?
