Trying to upload any graphics such as screenshot, icon, Feature graphic and I keep having the same error from from Google while my picture have the right spec. message is "Upload Error" "You need to check that your screenshot image is valid valid" or "You need to fix your feature graphic is valid"
Anyone has the same error or any clue?
I've even used another graphic from another app published and it still dont want it anymore. I've also deleted my app and create a new one in the Dev account. Same issue. I'm desperate.
I have the same error. Try with another browser. Firefox works for me.
Update: It seems to be working now. I was facing the same problem just an hour ago and now i'm able to upload screenshots
