Uploaded MSIX has generic errors
The list of errors I get is:
You must upload at least one package. If you are using market groups, then each market group must have at least one package.
You must provide a package that supports each selected device family (or uncheck the box for unsupported device families). Note that targeting the Xbox device family requires a neutral or x64 package.
The package DataMystic.WordPipe.msixupload is taking a long time to process. If this isn’t completed soon, try refreshing the page, or remove the package and then upload it again. If you continue to see this issue, contact support.
You must fix all package validation errors before submitting.

I am wondering if there is a mismatch between the Package/Identity/Publisher in the App Store Submission settings, CN=0450C09A-9234-4278-A26F-336E0FD3FA66, and what my code signing key uses,
and what is in my App Manifest.xml for my code signing key:
<Identity Name="DataMysticPtyLtd.WordPipeSearchandReplaceforWord" Publisher="CN=DataMystic Pty Ltd, O=DataMystic Pty Ltd, S=Victoria, C=AU" Version="10.4.0.0" ProcessorArchitecture="x64" />
The Name is identical in both locations, but the CN is different.
The CN must be as shown in the store, or there will be a problem after you upload to the store.
You can create a private cert with the correct CN in powershell using New-SelfSignedCertificate
Here is a powershell script that will create a password protected private code signing pfx file. It prompts you for the necessary information. It must be run elevated. It comes from our training class.

pause- Thanks Tim, that's awesome. I followed your steps to create a self-signed cert, but unfortunately I get exactly the same errors after uploading the .msixupload file. Will have to try and get support from Microsoft somehow.
The instructions are as clear as mud; so many make simple mistakes. Pay close attention to the following:
- The field from the store Package/Identity/Name must be identical to the PackageName field of the AppXManifest.
- The field from the store Package/Identity/Publisher must match that of the Publisher field of the AppXManifest, and also match the Subject Name on the certificate. All three must use the CN= format.
- The store Package/Property/DisplayName should be the same as the publisher display name of the AppXManifest, however I doubt anyone checks that.
- The msix file must be signed using the certificate with that subject field and either the certificate must not be expired, or you used a timestamp on the signing (although as you just created the cert, expiration should not be an issue).
