iTunes: Failed to create an app icon

Question

I am having this problem today when I tried to update my iPad app in iTunes. First it asked me to upload an application icon (which already existed, but they needed other), 1024 X 1024. I have uploaded non-alpha, non-layered, no-transparency image, upload succeeded. But when I hit "Save" it continuously gives me: "Failed to create an app icon error." I have tried png, jpg, same error. There is no other, detailed info on this error. Anybody can help me what is going wrong? Never had this problem before.

Answer 1

So here is what worked for me:

I used Chrome, but waited a minute AFTER uploading the icon, BEFORE pressing the save button.

My theory: I was pressing save immediately after the upload preview icon appeared. Perhaps the icon preview area displayed a thumbnail of the icon on the screen before the upload had been completely processed in the iTunes Connect backend.

Hope this works for someone else.

Answer 2

Same Problem, changed to Firefox and it got fixed. I was working with Chrome.
