Does anyone know how to rotate the photo on a profile page? No matter what I do (rotate the photo 360° on my photo viewer and other suggestions) it's still at 90°! Doesn't look good professionally and I can't find any information or contact for Upwork to ask how to get it right.
Rotating the photo on your photo viewer would not have any effect, unless you are able to save the rotated image.
You would need to use a program that can edit or save the photo, then upload the new photo.
