Same issue here. Team ID: 9PJ9T53NSV.
I tested with TWO completely different apps:
RouteCast (Flutter, Apple ID 6802804674) — builds 6, 7, 8, 10
ErkanTestApp2026 (native Swift Hello World, Apple ID 6804722287) — build 1
Both fail with "The requested app is not available or doesn't exist."
Multiple devices tested (iPhone 13 iOS 26.6 + friends' devices, no MDM).
Apple Support Case: 20000141592306. No response yet.
This confirms it's an Apple backend issue, not app/framework-specific.
