Marketplace Offers - Upload of .app taking a long time

I've had a hunt for an answer for this and can't find anything. 

 

I have a BC365 "contact me" offer that I am creating via MS Partner Centre.  I am on the Technical Configuration page and am required to upload a .app file.  I have the file, titled "Name of App_1.0.0.0.app".  When I upload it to the page the app is listed, however the page does two things:

  1. A stream of dots ....... travels along the top of the page, as if it is still busy "doing something"
  2. The Save Draft and Review and Publish buttons are greyed out

I've been sitting on this page for 30 mins or longer.  When I navigate away from the page I am warned that changes may not be saved, and if I continue to navigate away and come back to this page, I lose the file I am attempting to upload.

What am I missing?

Thanks

Janie

    You're not alone — this is a known pain point many Microsoft Partners encounter when trying to upload .app files in the Partner Center offer configuration for Business Central (BC365) "Contact Me" offers. Here's a breakdown of what might be going wrong and how to fix or work around it:

     

    Common Causes & Fixes

    Browser Compatibility Issues

    Partner Center can behave poorly in certain browsers or extensions.

    Try:

    1.Using Microsoft Edge (InPrivate/Incognito mode).

    Disabling any ad blockers or extensions.

    Clearing your browser cache or using a clean browser profile.

     

    2.app File Metadata or Signature Issues

    Even though the file is named correctly, Microsoft has strict validation rules.

     

    Ensure:

    The .app file was compiled using the correct target version of Business Central (matching your offer).

    You’ve signed the app with a valid certificate (if required).

    You generated the .app using the correct toolchain version (AL compiler for your target BC version).

    Run this from PowerShell to check the app’s metadata:

    Get-NAVAppInfo -Path "Name of App_1.0.0.0.app"

    Or use:

    alc.exe --analyze

    3.App Already Published or Duplicate Version

    Check if:

    The version already exists in your listing.

    You’re uploading a duplicate version number (1.0.0.0), which can silently fail.

    Solution: Bump the version (e.g., 1.0.0.1) and try again.

     

    4.Partner Center Backend Bug

    Sometimes, the Partner Center UI simply hangs due to backend issues, and nothing you do will fix it except re-uploading later or via another environment.

    Try:

    Refreshing the page after 10–15 minutes, which may "unlock" the save buttons.

    Logging out and back in.

    Trying from another Microsoft Partner tenant user account (if you have multiple).

    Temporary Workaround

    You can try uploading your .app file via Partner Center APIs instead of the UI. Microsoft offers APIs for managing commercial marketplace offers, including uploading technical assets.

    API Docs: Commercial Marketplace APIs (Azure) – Microsoft Docs

    If it persists even after the steps above, raise a support request:

    Microsoft Partner Support:

    Go to: https://partner.microsoft.com/en-us/support

    Choose “Marketplace offers” as the category

    Mention the exact steps and attach the .app file metadata
