Hi,
The Dev profile page is great but there are two bugs with it,
- The Header Banner pixel aspect of 1920 X 800 is completely wrong.
Its way too big.
I had to try several different pixel aspects to make it kinda work.
Using 72 dpi and Microsoft Edge browser. - The header banner pic shows up in the top left corner while logged in but
as soon as you log out its not there.
I attached two screen grabs thank you
