We have an app that is ready to be published. Only problem is that the app previews on ipad are hanging when we play them back in app store connect. Occasionally they play in full but most of the time they play a few seconds then hang or don't play at all. The resolutions are right. The bit rates are actually below the 10-12 mbps and the uploads are accepted. Furthermore when we have submitted the app to apple they have accepted it. It was only on some last minute tests before release that we noticed that the ipad videos were hanging.
Has anyone got any ideas what might be going on?
Thanks!
