"To upload app preview, you must use Safarin and OS X 10.10" - this error pops when I'm trying to upload a video.
Obviously, I am.
The video file is MOV, portrait 1080x1920, H.264. if anything is wrong with the video, the error don't tell me that.
Anyone seen anything like that before?
What platform(s) are you submitting video previews for?
What is the file size?
What is the run time min/max?
Always do anything with Safari. I try to upload the same video (resolution, duration are all fine) failed to Chrome. But get passed by using Safari.
