Today I tried to upload a profile image. That should be easy, right? Well I clicked "settings" and had to log into steemit wallet, which is for whatever reason a different page from Steemit (Problem #1). Then I was told to login using my "Posting Key." So I did. Then I uploaded a profile pic, and tried to click "update."
The button was grayed out. I was told the key I logged in with did not have sufficient permissions to do this. So I logged in with my active key. This redirected me to the wallet main page, where I clicked "settings," and saw... ...the steemitwallet login page again. I repeated this process twice before realizing it was a loop (Problem #2). Thinking maybe I was using the wrong key, I tried logging in with all four of those strings of gobbledygook called "keys" that the site spat at me when I joined (Problem #3). Not a single one gave me sufficient "permissions" for the simple act of adding a profile pic (Problem #4).
After waiting two weeks for my account to be approved (Problem #5) and spending a day on this site, I really am thinking I have utterly wasted my time. I don't believe I've ever seen a social media site so badly designed.
AFTER ACTION EDIT:
So the final verdict is simply that the image I was using was too small. Frankly, this seems to be another rather ridiculous restriction, but whatever. :-/
