After upgrading to macOS 26, I cannot install or update my app from either the App Store or TestFlight. Other apps update and install normally.

Steps:

Before upgrading, the app was installed via TestFlight and worked fine.
After upgrading, I tried to update the app from the App Store: The update stalls at ~90% and never completes. Other apps update successfully.
I launched the already-installed TestFlight version — it worked.
After deleting the app, I tried reinstalling from TestFlight and got the error: “The app couldn’t be downloaded. Try again.”
I tried rebooting, logging out/in of my Apple ID, and submitting a new TestFlight build — same issue.

Environment:

Originally built with Xcode 14
Also tried a new build with Xcode 16

App is compatible with macOS 26. Distribution outside the App Store (Developer ID signed and notarized build) runs fine

I see issue in TestFlight log:

A coordinated app install already exists with intent IXCoordinatorIntentUpdating (creator App Store)
but request by appstoreagent was for intent IXCoordinatorIntentInitiating

NSLocalizedFailureReason = Coordinated install exists with different intent.

I retried the download today and it works now without any extra steps on my part. I did update macOS — it’s possible that change helped. I’ll consider the issue resolved for now. I also submitted a bug report via Feedback Assistant (though I haven’t heard back yet).
