Hellooo! I see other people are having this problem too! Well, I just tried uploading my own avatar, meeting the requirements and well under 15kb and it looks like it uploads but I don't find it anywhere in the dropdown or the 'view all avatars' section. There's a lot to go through, but I did and didn't see mine there. I tried uploading it a few days ago (originally) thinking maybe the admin team had to process it before it became avail. but I went to check and still didn't see it. Tried uploading it again with the same problem -- it's just not there. I hope this gets fixed soon! =DD
