I am trying to upload the App Icon.
The file that i am uploading is as per the explained criteria. Its a PNG file and of size 1024*1024 pixels size. I have tried multiple times to upload the file.
It is not showing any error yet i see no "save" button after i choose a file.
Here is how it looks after i choose a file. There are no errors, no file name and no save button on the dialog.
Update:
It was Facebook's Bug which is resolved now.
Its already reported as a bug in facebook developer support. Your are not the only one hving that problem. If you see in the browser console, when you choose a file it gives a CORS problem
