I did build a demo project and can see that the problem only appears if new diffabledatasource gets use. Maybe I'm doing something wrong, still investigating.

I found a workaround: the problem does appear if I user UiCollectionViewController as a base class I use a custom init() to setup UICollectionViewCompositionalLayout and call super.init(collectionViewLayout: layout) with my layout the layout looks exactly as I wanted but the stepper behavior is wrong If I use a UIViewController as a base class, it works as expected.

Same here

I can't select a price tier and can't update any in app purchases because it will claim the price is not setup correct. Also the table listing all tiers to prices in different regions is not loading.

Since 4 days I con't set prices in AppStore connect. this block the submittion of your app. Sadly nothing has. solved this issue right now. @Apple when will you look at the issue?

Still not working here
