Hi, Unity Tech guys, My project name of Unity(5.3.3f1) has a blank(space character), it can be exported/packaged right, but it will bring a certification failed in Windows Dev Center dashboard when I submit for approval, so I think it's a bug. After I remove this blank(space character) as "AncientContinent", it's OK. Unity exports Visual Studio project files by this project name configure, maybe some problems would be generated at that time as that format. Just report. I don't know how to open a issue(bug) tracker, so I start a new thread here to let you know.
