Different symptom, possibly the same subsystem. On my app Product.products(for:) and Storefront.current both never return at all — no error, no timeout, no result — on every device, Apple Account and storefront I have tried, 100% of the time since launch. Product metadata never loads, so it fails before the payment sheet the rest of this thread describes.
App Apple ID 6802240269, storefronts AZ and TR, iOS 26.6. Filed as FB24488724 with a sysdiagnose, and as Developer Support case 20000143122321. Separate thread with full details here: https://developer.apple.com/forums/thread/844232
