Brief description of your issue

My Microsoft Store application "Well of Legends" (Product ID: 9NNZR5BZQJ42) is published and publicly available in the Microsoft Store, but it cannot be discovered through the WinGet msstore source.

A known-good Microsoft Store package (Company Portal, Product ID: 9WZDNCRFJ3PZ) is discovered successfully from the same machine and the same msstore source.

Microsoft Dev Center Support investigated this under case 2607280050002589 and asked me to report the issue to the WinGet team using the msstore tag.

Steps to reproduce

1. Reset and update the WinGet sources:

winget source reset --force
winget source update

2. Verify that a known-good Microsoft Store package can be retrieved:

winget show --id 9WZDNCRFJ3PZ --source msstore --accept-source-agreements

Result:

Found Company Portal [9WZDNCRFJ3PZ]

3. Search for my published Microsoft Store application:

winget search --id 9NNZR5BZQJ42 --source msstore --exact --accept-source-agreements --verbose-logs

Result:

No package found matching input criteria.

4. The same issue occurs with:

winget show --id 9NNZR5BZQJ42 --source msstore --accept-source-agreements

The application is publicly available in the Microsoft Store.

Expected behavior

WinGet should discover and return the Microsoft Store package for Well of Legends when queried using its Store Product ID 9NNZR5BZQJ42 through the msstore source.

Actual behavior

WinGet returns:

No package found matching input criteria.

Verbose logging shows that WinGet successfully sends a request to:

https://storeedgefd.dsx.mp.microsoft.com/v9.0/packageManifests/9NNZR5BZQJ42?Market=CZ

The Microsoft Store backend responds with HTTP 200 OK, but no package manifest is returned.

The log then reports:

No manifest results returned.
Search result size: 0
No app found matching input criteria

and terminates with error:

0x8a150014

A known-good Store Product ID works correctly through the same msstore source.

Windows Package Manager v1.29.290
Windows: Windows.Desktop v10.0.26200.9168
System Architecture: X64
Package: Microsoft.DesktopAppInstaller v1.29.290.0

Start by reproducing the issue with winget source reset --force, winget source update, and the reported winget show and winget search commands against the msstore source. Inspect the linked verbose log and the packageManifests request; the issue is done when Product ID 9NNZR5BZQJ42 returns a manifest and is discoverable through msstore.
