Don't make it an editable field if you can't change it. Also, please let us change it. I don't like getting emailed at my deadname.
Change email when?

That doesn't do anything. After hitting submit it just reverts.

You need to confirm the email address, as it states:
The changes have been saved. Email address changes, however, are not reflected immediately until verified from the new email account. Please check your inbox for a new email with further instructions.

Aaah. The message is really not obvious and the emails went to spam. Cheers

I changed my email address two days ago. No issues. Just took 30 minutes to update on the site.

Still nothing after an hour and a half. I think it's broken.

I have to ask but is there anything in the SPAM folder?
If not, can you start a thread in TWAM and give us the email address you are changing to?

Implying it wasn't done on purpose

Incorrect. I implied that it was done on purpose and it doesn't work.

Oh true!!
If you wish to change your email address, you can do so in My Account - E-mail address: ., enter the new email address in the text field and click submit at the bottom.
