I am trying to upload an App Preview to App Store Connect for a iphone app,I created the preview as an "App Preview". When I try to upload the app preview I get the message " your app preview is too big". The preview is 30 sec. It is 6 MB in size. MP4 format. Who know how to change my app preview
I am facing the same issue. 1st preview of 8 mb got upload and processed successfully, but after that the other 2 of 4mb and 6mb are not.
You need to put the video through iMovie and export it as App Preview. Then ASC should not complain.
I put my video through iMovie and saved as App Preview and I am STILL getting the "too large" error message - the file is 18.9 MB, 2:05 long.
Nevermind. I see now it has to be 15-30 seconds.
