I searched and searched for an answer to this very question. Unfortunately, I always found the same answer, and my avatar never changed. But I finally found a way to change it walgreenslistens. How does one do this? After changing the avatar in the Settings.
I decided to contact support about the issue. All you need to do is log out of curseforge, and log back in. It worked for me. If it doesn't, I would recommend contacting support yourself: https://support.curseforge.com/
