I just put a signature and an avatar on my user cp and it isn't showing on any of my posts, what am I doing wrong?

are you on the app or the desktop

 

your signature is showing up online

 

Signature is there now but my avatar still isn't showing up, I don't know what I'm doing wrong, I'm on the full site, but I am running it on my iPhone, I guess I need to get the app. Any help on how or what to download for the app wod be apreciTed
