I can't seem to find any option to change my avatar anywhere, any help with this would be appreciated.
try to change your avatar now, following the steps from @Pet_The_Lizards and see if you're able to do it
Go to your profile.
Click the red silhouette icon (next to your picture on a computer, under your picture on a phone).
Click "Edit Profile"
Click "Change Picture".
Go crazy. 🦎
The option for that isn't there it only says preferences.
"Preferences" and "Change my picture" should be directly next to each other.
For me it only says
change my password
in that order.
you probably need to confirm your email address then, as that sounds like it's not been verified.
I did confirm it but I tried asking for another confirmation email for the sake of it just now and got a message saying I don't need confirmation.
Well, if you already confirmed it, then I guess all you can do is wait for it to show up.
That worked, thanks to the both of you.
