The app is approved and "Ready for sale", but there is a lock icon next to Description and I can't make any changes. Other fields like "Promotional Text", "Support URL", etc are editable.
I've read a lot of conflicting and old information about this. Any help would be appreciated
You cannot able to edit description and few other fields here without Apple’s approval(review), and to edit you have to upload a new version.
