Changed profile avatar, but HN keeps showing the old one


I have changed my profile avatar, but when I open one of my stories it shows my previous avatar.

Is there anywhere else I need to change something ?
I emailed the support couple of times, but got not return.
Any clue ?

Why no one form HN support is responding to my emails or answering to this post ?

It seems updated avatar on doesn’t get echoed on
I’m not going to expose my guessing on how things are implemented server-side, all I need is to have my new avatar everywhere on HK website.
Thanks for your attention.

Hello, should be all set. May need to clear your cache.
