In-App Purchases and Subscriptions section missing from version page — first-time submission, all configurations complete

My app Comic Locker - Track & Value (Bundle ID: com.kevinmillerxi.thecomiclocker.app) is a first-time submission with two auto-renewable subscriptions. Version 1.0 is in 'Prepare for Submission' with build 21 attached. Both subscriptions (Pro Monthly and Pro Annual) are configured under the 'Comic Locker Pro' subscription group with full localization, pricing, review screenshots, and availability set to all countries. Paid Apps Agreement is active. ITA Part XX compliance is active. However, the 'In-App Purchases and Subscriptions' section does not appear in the main content area of the version page. The Monetization section (In-App Purchases, Subscriptions) shows in the left sidebar, but there is no way to attach subscriptions to the build on the version page itself. I've tried multiple browsers (Chrome and Safari), uploaded a new build, and updated the version number. I also confirmed via sandbox testing on a physical device that Product.products(for:) returns empty for both product IDs. I've seen similar reports in threads 804327 and 820936. Any help is appreciated.
