Package Upload Issue While Submitting New Build to Microsoft Store

Question

Dear Microsoft Store Support Team,

We are currently facing an issue while uploading packages for a new build submission on the Microsoft Store.

While attempting to upload the packages, the upload process is extremely slow and takes an unusually long time to complete. In some cases, the upload does not complete at all.

We have already tried the following from our end:

Verified internet connectivity and upload speed

Attempted uploads from different networks and locations

Retried the upload multiple times

Despite these checks, the issue persists, and the packages are still taking a very long time to upload.

We wanted to check if there is any ongoing issue on the Microsoft Store side related to package uploads or if there are any recommended steps or alternative approaches we should follow to successfully submit the build.

Please let us know if you need any additional information such as the app name, submission ID, package size, or logs/screenshots from our side.

Looking forward to your guidance and support.

If you are experiencing slow upload speeds or failures while submitting packages to the Microsoft Store, there are a few things you can consider:

1. File Size and Type: Ensure that the packages you are trying to upload are within the size limits and are of the correct file types (.msix, .msixupload, .msixbundle, .appx, .appxupload, and/or .appxbundle). Large files can take longer to upload, and incorrect file types may cause issues.
2. Network Stability: While you've already verified your internet connectivity, consider checking for any network throttling or restrictions that might be impacting upload speeds. Sometimes, corporate networks may have policies that affect large uploads.
3. Package Validation: If there are issues with the package itself (e.g., validation errors), this could cause the upload process to hang or fail. Ensure that your packages are correctly built and validated using the Windows App Certification Kit (WACK) before attempting to upload.
4. Microsoft Store Status: Occasionally, there may be ongoing issues with the Microsoft Store that could affect uploads. Checking the Microsoft service status page or forums for any announcements regarding outages or maintenance could provide insight.
5. Alternative Upload Methods: If the issue persists, consider using the Partner Center directly to upload your app package instead of through WACK, as this might yield better results.

If none of these suggestions resolve the issue, it may be beneficial to gather logs or screenshots of the upload process and contact Microsoft support for further assistance.
