I spent my whole day trying to upload screenshots of my newly created application.
Every time I try to upload a phone screenshot (PNG - 24bit 1920x1080px) it shows an error: 'You should check your screenshot is a valid image'...
Am I doing something wrong or is this a common issue? How do i fix this?
It is working now, repeating the same process. I guess the developer console wasn't working correctly during the entire day untill now...
Could your image possibly have an alpha channel? The Google Play graphic asset guidelines also state that 24bit PNGs must not have an alpha channel.
