This may well be the case, but when we first set up our email addresses 20+ years ago, no-one knew how things would evolve (phone apps etc) and that our email addresses would become our User IDs for almost every account we ever opened. Most websites let you change your contact email address but it is almost impossible to change your User ID online. Have you tried changing your email address for 100 or more accounts, many of which you cannot remember setting up? Your answer may be true but it is rather trite and does not help with the current BT/EE migration problem. I have four family email addresses on my BT account and we all use our phones to access them. Do not want to be forced to use the website - this is a backward step. I will not be migrating until they sort this out.
