Uploading a png doesn't seem to work when uploading a new profile image. It appears to take, but as soon as your visit another page or reload if reverts to the previous profile picture. Using desktop at the moment.
When using a jpg everything works as expected and the profile picture sticks.
Works from phone
I usually put a png over a background of my choosing and convert to jpg. I do this because the program your using will usually default a white or black color around you png and it doesn't always look good.
Thank you for this feedback, Ill look into it.
