My UWP app is ready to be submitted to the Microsoft Store. I created the package in Visual Studio and tried to submit to the store. Validation generated the error message below. Where and how can I correct this package data?

Invalid package family name: 6875WeCanAppsSoftware.WeCanSpeakPro_33cde44ccwfew (expected: 6875WeCanAppsSoftware.WeCanSpeakPro_g41babarqva5y)

Invalid package vendor name: CN=WeCanSpeak (expected: CN=8E59FA6F-E96D-4F39-ACA6-0D0D32F78F0B)

The problem is that the current certificate is not valid, You can check whether the package family name in Partner Center is the same as that in Package.appxmanifest.

It is recommended to associate the app with the store. When you associate your app, some of the fields in the Packaging tab of the manifest designer are automatically updated.

1.Right-click your project name in Solution Explorer

2.Choose Publish->Associate App with the Store (before Visual Studio 2019 version 16.3, the Publish menu is named Store).

3.On the select an app name page, select the current project app.
