Whenever we submit a new release to the App Store we get a nag email from Apple that states, "The app binary listed below was 199.2 MB when you submitted it, but will be 223.9 MB once processed for the App Store. This exceeds the cellular network download size limit and may require your app to be downloaded over Wi-Fi." However, when I download the app from the App Store and have the Settings set to "Alway Ask" on my phone the alert shows 129 MB, which is matches up closely with what we see in the TestFlight metadata for all device types except "Universal". What is "Universal" device type in these days of thinning? And why is Apple apparently using that number to generate the nag email?

I was about to finally sign up for the Apple Music affiliate program since one of my apps does provide the MusickKit Subscription Offer. However, it looks like it was renamed and restricts usage to only artists and record labels. (https://partners.applemediaservices.com) Is this correct? Can I as an indie developer not earn commission of Apple Music that I drive from my apps?

I am trying to get the playbackStoreID via the MPMediaPickerController so I can play songs in my app. For many songs I can see and select I am getting a value of "0" for the playbackStoreID on the returned MPMediaItem. Now if I use the "Music" app I can play those songs, but since the playbackStoreID is "0" I cannot successful get them in the queue for a MPMusicPlayerController.applicationQueuePlayer What's the deal? How do I get a proper ID that I can use to get those songs played? If I cannot, how can I hide those songs from the MPMediaPickerController so a user does not think they can play those songs in my app?
