if you're still looking for the right solution then follow this official guideline here https://support.wix.com/en/article/changing-your-wix-user-name-6081052
First you click on the person thing at the bottom right corner, then you click “view profile” then click “Edit” and then change whatever you want; email, username, logo, about......
You can't seem to edit your user name anymore. It shows up in the URL as the email you signed up with. Very frustrated with this new change.
This is also my issue. Although you can change your username, the URL still shows your email address. So you have to be careful when you want to post something anonymously. Because people can still see your real name from the URL if your email address contains your real name. I contacted wix but they haven't been very helpful. @AB Photography If I click your profile, I can see from the URL that your name is Alec Butte.
When you sign up you give an e-mail address and password. But then when you make posts your e-mail address shows!!! No one likes that. How do you either change your e-mail name to a Username you like or choose a Username when you sign up? Thank you!
You go to the post settings and go to author and press “+ add an author” and then design it
