I tried the new version. I can click on my avatar in the account interface, but I am a musician, so the musician interface appears, and then I continue to pull down. There is a basic information bar with a button on the right. For more information, click on the top right corner and edit.
Click the button account on the far right below the app, and then edit it on the far right of the avatar button. You can change it inside. Learn how to modify my artist information, click Enter, and then follow the prompts.
