I added audio to this app preview. Shorten it's time to 28 seconds just incase it was a few frames over 30 secs. It is an iPad Pro 2nd gen app preview. It's resolution is 1200 x 1600 because the app is a landscape app. This is correct according to the "App Preview Specifications. https://help.apple.com/app-store-connect/?lang=en/#/dev4e413fcb8
I am using macOS Monterey 12.0 beta and Safari 15.0.
I still get no errors when I try and upload my app preview in App Store connect. It just does not acknowledge there is a file being dragged into the upload area or that I have chosen a file to upload.
Screenshots upload fine.
Does anyone have any suggestions?
