Hello, I wanted to change my email here but I got a email change failure. I did as what is instructed in the error but I'm still unable to change my email. Help

I'm having the same issue — I received the email with the link, but got the "Sorry, we couldn't confirm your email address. Please try copying the full link address from your email to the clipboard, and then paste it into the address bar." error both when I clicked it and when I copy-pasted the link.
