[iOS] Custom App Icon still renders as white square

I am following up on a rendering issue where my custom app icon appears as a blank white square on the iOS client.

Current Status:

Despite following the standard guidelines, the icon fails to render on iOS (Works perfectly on Android/Desktop).

What I have tried (and failed):

• Changed accentColor: Updated manifest from #FFFFFF to #4B6BF5 (Brand Blue) to avoid white-on-white issues.
• Version Bump: Increased manifest version from 1.0.17 to 1.0.18 to force cache invalidation.
• Re-installation: Completely uninstalled the app on iOS, cleared app data, and re-added it.
• Direct Upload via Teams Admin Center: I tried uploading the app package directly through the Admin Center, but the icon still fails to render on iOS.
   
• Commercial Marketplace: I have users who installed the app via the Commercial Marketplace, and they are also seeing a blank icon.
   
• "Publish to Org" via Developer Portal: I also tried the "Publish to Org" feature within the Developer Center, and the result is the same.

Icon Validation:

Manifest Snippet:

{ "version": "1.0.18", "manifestVersion": "1.22", "id": "e4fae5da-30ea-4f90-9eae-807b2a13a127", "icons": { "outline": "outline.png", "color": "color.png" }, "accentColor": "#4B6BF5" }
