Can't change email

I signed in with a google account the first time I entered the website. I did a couple of lessons and realized that I signed in with the wrong account. I want to change my email, but due to signing in with a google account, I think that there’s problems with changing its email. I went to the “change email” section and typed the email I wanted and got the link. However, when I sign in with the new email, my progress has been lost. Is there a way I could change the email of this account?

are you sure you changed the email? maybe you need to try again

or you will need to contact support at
