I have added all required details along with app name, description, screen shots, etc. Still at time of submission it gives error that you need to set all required details.
Strange behaviour I notice is that when I am land on app market Details page for application by default it displays all details as blank and when I try to set details on any field just loading dialog is running nothing happen after long time. Once I select English (Canada) then I can see all details which I set.
note : I can only see English (Canada) option on top. There is no other option visible. Also I have just set price for USA only.
