Hi everyone,
we are currently facing an issue with one of our apps regarding the new icon requirements in iOS 26. • We created the app icon using Apple’s Icon Composer. • On the device, everything works perfectly: the app icon is shown on the home screen, and it can also be customized with the new iOS 26 features (colors, transparency, etc.). • However, in TestFlight the app icon is not displayed at all (in the TestFlight app on the device). • In App Store Connect, the icon is also not shown in the overview for the app. Interestingly, within the list of TestFlight builds in App Store Connect the icon is visible.
What we have tried so far: • Created an archive and manually uploaded it to App Store Connect → no icon in TestFlight. • Took the working Icon Composer asset from another app target where everything works correctly, deleted the old one in this project, and copied the working asset into the problematic target. → Same behavior: visible on the device, but still missing in TestFlight and App Store Connect overview.
In contrast, in another app (using the same workflow and also Icon Composer), everything works perfectly: the icon shows up on the device, in TestFlight, and in App Store Connect.
Has anyone experienced a similar situation? Is there something specific that needs to be set in App Store Connect (e.g. Marketing Icon / Branding section), or could this be related to the new iOS 26 icon handling?
Any help or hints would be greatly appreciated.
Thanks in advance!
