call-for-help: we are keep getting the illustrated error after hitting "save changes" in the application settings dashboard ... the changes are saved though ... any link where we can report our app issue?

This is not a problem with your app.. This happens sometimes because your app server might have taken a longer time to update on FB servers and the connection timed out... Nothing to worry about you an try again

I had the same issue and solved it by checking all the icons and screenshots. I made sure that they all was in the same format (.png) and then it worked!

I guess the issue, for me, is that i used different formats.
