Persistent iOS Signing & UIBackgroundModes Entitlement Issue

Problem Statement

We are experiencing a critical and persistent issue preventing the successful signing and building of our iOS application. The core problem is that provisioning profiles, whether automatically generated by Xcode or manually created in the Apple Developer Portal, consistently fail to include the UIBackgroundModes entitlement, leading to a build failure.

Specific Question

Why are provisioning profiles generated via the Apple Developer Portal and/or Xcode's automatic signing process consistently omitting the UIBackgroundModes entitlement for our App ID, even when this capability is explicitly configured in Xcode? We seek guidance or backend intervention to ensure our provisioning profiles include the necessary entitlement.

Expected Outcome

We expect to be able to successfully build and sign our iOS application, with provisioning profiles that correctly include the UIBackgroundModes entitlement, allowing for proper implementation of remote notifications.

Observed Symptoms

Primary Build Error: Consistent build failure with the exact error message: "Automatic signing failed: Provisioning profile 'iOS Team Provisioning Profile: com.scott.ultimatefix' doesn't include the UIBackgroundModes entitlement."

Missing Entitlement in Profile (Confirmed by Inspection): Direct inspection of downloaded .mobileprovision files (including those manually generated in the Developer Portal for com.scott.ultimatefix) consistently shows the absence of the <key>UIBackgroundModes</key> entry within the <dict> section of the Entitlements dictionary. The aps-environment key for Push Notifications is present, indicating Push Notifications are enabled, but Background Modes are not.

Certificates Correctly Recognized in Xcode: Our "Apple Development: Stephen Criscell Scott" and "Apple Distribution: Stephen Criscell Scott" certificates are correctly displayed and recognized in both Keychain Access and Xcode's Preferences > Accounts > Manage Certificates window (without "Not in Keychain" status). Furthermore, the Signing & Capabilities tab for the target in Xcode now correctly shows Signing Certificate: Apple Development: Stephen Criscell Scott.

Persistent Issue Across Resets: The problem persists despite extensive local cache invalidation, Xcode reinstallation, and even testing in a fresh macOS user account (which confirmed the issue was not user-specific).
