I've started seeing it too while playing audio with AVPlayer. Anyone found a solution yet?

I just ran into this too. The way I was able to get around it was to edit the SplitViewController in the storyboard and set the Style to 'Unspecified'. I think this is the 'classic' mode for SplitViewControllers, as opposed to the 2-column vs 3-column styles that Apple is now encouraging. I think maybe the "Build For iPad" WWDC video explains the roadmap for where SplitViewControllers are going. We will all eventually have to rethink how our UI's work.

Thanks, that makes a lot of sense. And yes, the purchase of the metadata will make a significant difference in the appearance and functionality of my app. But until I hear something "official", I feel like I'm just guessing. Everyone's app is different and who is to say what is appropriate for a screenshot? Would someone from Apple like to chime in here and clear up the matter?

Thanks again, endecotp. I really did appreciate your answer and hope I didn't seem ungrateful. I think you are right and I might as well proceed with taking screenshots using my best judgement. I've already put the issue to Developer Support and they were really helpful, but weren't able to give me a definitive answer about what is expected when the "item or service" is a json file. To be fair, it was over the holiday weekend when they are not fully staffed. My support staffer did commit to using my case as a form of feedback to the App Review teams. Hopefully this will result in Apple making it more clear what they want to see in these screenshots. We also agreed that the Developer Forums would be a good alternative and I was pretty thrilled to get an answer here within 1 hour. So I'll take your advice and not waste time waiting for Apple to "chime in" here. Again, many thanks!

Xcode 16 seems to have broken some things with regard to SKConfiguration file syncing. I have been unable to get mine to sync at all since the upgrade.

Thanks. Me too.
